Methods of TOC analysis include

1. Acid Digestion Method

The most common method for determining TOC is the acid digestion method. By acid treating a sample, usually with hydrochloric acid, which is strong enough to react with inorganic carbonates but does not react much with organic Carbon, the inorganic carbonate species within the sample will effervesce as Carbon dioxide. The acid-treated sample and a non-acid-treated sample can both be analyzed using either the LECO C744 series or LECO C832 series for Carbon content. The untreated sample would indicate the total carbon content, while the acid-treated sample’s Carbon content would be the remaining organic Carbon content. The difference between the two samples would be the total inorganic Carbon (TIC) content.

 

2. Temperature Dependent Method

Another Carbon determination method is temperature dependent. With the temperature dependent method, samples do not need to be pretreated. Organic Carbon combusts to CO2 between 150 °C and 450 °C, while inorganic species combust below 1,000 °C. The RC612 resistance furnace multiphase Carbon and moisture determinator performs this analysis by using a two-step temperature ramping at 450 °C and 1,000 °C without any acid pretreatment of the samples. The CO2 gases are swept through to an NDIR at 450 °C and again at 1,000 °C to determine the TOC and TIC in the sample.

FAQ – Separation Science

Answer:
Gas chromatography separates components in a mixture by utilizing a thin silica tube coated with a stationary phase. The components, carried by a gas (the mobile phase), move at different speeds based on their affinities for the stationary phase. This differential migration leads to the separation of the components, allowing for their individual analysis and identification.

Alternative response:

  • Gas chromatography is a technique for separating a mixture of volatile analytes
  • The analytes are transported by a mobile phase (the carrier gas)
    • Become distributed between the mobile phase and a stationary phase
    • The Stationary Phase is attached to the inside of a very fine column
  • Phases are typically characterised by their polarity
  • A polar analyte will be retained by polar column for longer than a non-polar analyte
    • and vica versa

Answer:
LECO uses Agilent 8890 chromatography. The gas chromatograph includes the following features:

  • Compatibility and perfect integration with the mass spectrometer
  • Automatic regulation of gas flows
  • Agilent supported inlets: Split/Splitless (SSL), Multimode (MMI), Programmable temperature Vaporizer (PTV) etc.
  • Programmable oven, up to 450 °C
  • Chromatograph compatible with Fast-GC
  • The GC is completely controlled by and integrated into LECO’s ChromaTOF software

Answer:
The LECO mass spectrometer is connected to the GC via a heated transfer line. The LECO GC-TOF allows you to have a 'full range' acquisition, without compromise, then a targeted and/or non-targeted data exploitation depending on what you want to do.

It consists of an EI (Electronic Impact) source, a 70 cm flight tube, a reflectron and a detector. Vacuum is provided by an internal turbomolecular pump connected to an external secondary pump.

Pegasus-BT-diagramm

Answer:
The mass range of the Pegasus BT is from 10 to 1500 m/z. All masses are collected all the time, unlike quadrupole instruments that collect a single mass at a time (quadrupole scanning mode is single ion monitoring, SIM, quickly scanning across the mass range).

Answer:
GC×GC-TOFMS can detect discrepancies in the composition of food products, helping to expose fraudulent claims of Halal certification and ensure consumer confidence in authentic Halal products.

Answer:
By examining the chemical composition of inks and pigments, GC×GC-TOFMS provides insights into the materials used in Islamic calligraphy and manuscripts, aiding in their preservation and authentication. An example of similar work can be read in this publication on analysing the paints used by Leonardo Da Vinci.

Answer:
LECO’s GC×GC-TOFMS system utilizes two columns with different separation mechanisms, providing enhanced chromatographic resolution for the analysis of complex mixtures. In one dimension the analytes are separated by polarity, or according to boiling point. An additional dimension separates according to an alternative property, of which there are many. This results in a 3D image – the two dimensions of separation and the abundance of the analytes in the third dimension.

Answer:
LECO's StayClean® ion source originates in the requirement for a fast source to match the speed of the TOFMS. Accomplished by reducing ion to ion interactions, such as with the walls of the source. The source was thus designed without walls – so there is nothing to clean. Massively reduced downtimes, especially for complex matrices and more reproducible results.

Answer:
Yes! With superior separation power and precision, LECO’s GC×GC-TOFMS system can uncover hidden details and confidently identify components, even in the most intricate mixtures:

  • Increases detectability
  • Removes analytes from matrix interference
  • Separates co-elluting peaks
  • Creates cleaner peaks, which match closer with libraries
  • Creates structured chromatograms thus further improving identification confidence

Answer:
The cryogenic Quad Jet modulator consistently delivers reproducible quantitative results not only within the lab but also between labs worldwide. This is achieved because:

  • There are two cold jets. So, eluent from the primary column does not flow into the secondary column by mistake
  • The distance between cold zones is identical in every system worldwide, unlike other systems that require manual adjustment and intervention
  • The modulation is completely computer controlled. This along with the 2 separate cold zones, allows for variable modulation periods in the same analysis, vastly improving separation across the chromatogram
  • In the same way the primary column is temperature controlled in the primary oven, the secondary column is also independently controlled, allowing for total control of the chromatogram along the entire column setup

These four features not only improve separation and control, they are also unique to the LECO QuadJet.

Answer:
By combining comprehensive two-dimensional gas chromatography (GC×GC) with high-speed, high-sensitivity time-of-flight mass spectrometry (TOFMS), LECO's GC×GC-TOFMS can separate and identify the complex mixtures of flavours and fragrances in food samples with detail and precision.

Answer:
Yes! LECO’s GC×GC-TOFMS is an excellent tool for non-intentionally added substances (NIAS) analysis in food safety. It allows for the comprehensive analysis of complex food samples, ensuring the detection and identification of potential contaminants and unwanted substances. For example, LECO’s MOSH/MOAH solution is widely recognised as the most comprehensive and rigorous analyser for mineral oil contamination in food stuffs.

Answer:
LECO’s GC×GC technology utilizes two stages of separation, significantly increasing resolution and analysis power compared to traditional gas chromatography. This allows for the detailed separation and identification of complex mixtures with unparalleled precision.

Answer:
LECO’s TOFMS technology offers excellent sensitivity, speed, and resolution in mass spectrometry. By fragmenting and ionizing analyte molecules and separating the fragments based on their mass-to-charge ratio, LECO's TOFMS enables highly accurate identification and detection of compounds in samples. The system not only records to a computer at high speed, it detects at a rate of 32,000 Hz thus producing a very high level of accuracy.

Answer:
GC×GC-TOFMS enables the analysis of dietary supplements for the presence of non-compliant ingredients, such as animal-derived gelatine, ensuring that the products meet the strict requirements of Halal certification.

Answer:
GC×GC-TOFMS is a valuable tool for monitoring air and soil quality near Islamic sacred sites, identifying pollutants that may pose a risk to their preservation and guiding conservation efforts. As an example, Imperial College London have utilised a LECO Pegasus BT 4D to identify microplastics in the air of London. You can read about it here.

Answer:
LECO’s GC×GC-TOFMS system utilizes Time-of-Flight Mass Spectrometry (TOFMS), which provides high-speed detection of ionized compounds based on their mass-to-charge ratio.

Answer:
LECO provides software for data analysis, enabling compound identification, quantification, and other types of analysis based on the mass spectra obtained from the TOFMS.

Answer:
LECO’s StayClean ion source, a standard feature in every Pegasus BT GC-TOFMS and GC×GC-TOFMS system, flushes neutrals and contaminants continuously. This virtually eliminates the need for routine maintenance, allowing you to spend less time on upkeep and more time on your research.

Answer:
Sample handling is crucial in GC-MS analysis. LECO employs advanced sample handling robots called Autosamplers that can handle samples in three dimensions of space. These robots ensure precise and consistent sample preparation, ranging from simple liquid injections to complex processes like chemical reactions, extractions, and accurate dilutions.

Answer:
The first GC-MS was a GC-TOFMS developed in the 1950s. However, the technique was too powerful for data recording at the time. In the mid-1990s the first GC-TOFMS capable of recording the data for processing was developed by LECO. This breakthrough in fast GC-TOFMS technology allowed researchers and analysts to utilize the capabilities of GC-TOFMS for their analytical needs.

Answer:
By combining two-dimensional separation, robust ionization, and high-speed TOFMS detection, and patented deconvolution algorithms LECO's GC×GC-TOFMS system offers a powerful solution for analysing complex mixtures with enhanced resolution, sensitivity, and separation power.

Answer:
By analysing the chemical composition of materials used in ancient Islamic artifacts, GC×GC-TOFMS assists in determining their authenticity, providing valuable insights into historical and cultural heritage.

Explore the Fascinating World of Separation Science

The very first GC-MS was a GC-TOFMS which was built in 1947. The information it provided was much too large to record, and it was not until the mid-1990s when LECO introduced the first fast GC-TOFMS, that GC-TOFMS became a useable tool for researchers and analysts. Followed a few years later by LECO’s introduction of the first GC×GC-TOFMS.

Today, LECO’s Separation Science products are recognised across the globe as leading advanced technology innovations in TOFMS Mass Spectrometry and Comprehensive two-dimensional Chromatography.

FAQ – Separation Science

Answer:
Gas chromatography separates components in a mixture by utilizing a thin silica tube coated with a stationary phase. The components, carried by a gas (the mobile phase), move at different speeds based on their affinities for the stationary phase. This differential migration leads to the separation of the components, allowing for their individual analysis and identification.

Alternative response:

  • Gas chromatography is a technique for separating a mixture of volatile analytes
  • The analytes are transported by a mobile phase (the carrier gas)
    • Become distributed between the mobile phase and a stationary phase
    • The Stationary Phase is attached to the inside of a very fine column
  • Phases are typically characterised by their polarity
  • A polar analyte will be retained by polar column for longer than a non-polar analyte
    • and vica versa

Answer:
LECO uses Agilent 8890 chromatography. The gas chromatograph includes the following features:

  • Compatibility and perfect integration with the mass spectrometer
  • Automatic regulation of gas flows
  • Agilent supported inlets: Split/Splitless (SSL), Multimode (MMI), Programmable temperature Vaporizer (PTV) etc.
  • Programmable oven, up to 450 °C
  • Chromatograph compatible with Fast-GC
  • The GC is completely controlled by and integrated into LECO’s ChromaTOF software

Answer:
The LECO mass spectrometer is connected to the GC via a heated transfer line. The LECO GC-TOF allows you to have a 'full range' acquisition, without compromise, then a targeted and/or non-targeted data exploitation depending on what you want to do.

It consists of an EI (Electronic Impact) source, a 70 cm flight tube, a reflectron and a detector. Vacuum is provided by an internal turbomolecular pump connected to an external secondary pump.

Pegasus-BT-diagramm

Answer:
The mass range of the Pegasus BT is from 10 to 1500 m/z. All masses are collected all the time, unlike quadrupole instruments that collect a single mass at a time (quadrupole scanning mode is single ion monitoring, SIM, quickly scanning across the mass range).

Answer:
GC×GC-TOFMS can detect discrepancies in the composition of food products, helping to expose fraudulent claims of Halal certification and ensure consumer confidence in authentic Halal products.

Answer:
By examining the chemical composition of inks and pigments, GC×GC-TOFMS provides insights into the materials used in Islamic calligraphy and manuscripts, aiding in their preservation and authentication. An example of similar work can be read in this publication on analysing the paints used by Leonardo Da Vinci.

Answer:
LECO’s GC×GC-TOFMS system utilizes two columns with different separation mechanisms, providing enhanced chromatographic resolution for the analysis of complex mixtures. In one dimension the analytes are separated by polarity, or according to boiling point. An additional dimension separates according to an alternative property, of which there are many. This results in a 3D image – the two dimensions of separation and the abundance of the analytes in the third dimension.

Answer:
LECO's StayClean® ion source originates in the requirement for a fast source to match the speed of the TOFMS. Accomplished by reducing ion to ion interactions, such as with the walls of the source. The source was thus designed without walls – so there is nothing to clean. Massively reduced downtimes, especially for complex matrices and more reproducible results.

Answer:
Yes! With superior separation power and precision, LECO’s GC×GC-TOFMS system can uncover hidden details and confidently identify components, even in the most intricate mixtures:

  • Increases detectability
  • Removes analytes from matrix interference
  • Separates co-elluting peaks
  • Creates cleaner peaks, which match closer with libraries
  • Creates structured chromatograms thus further improving identification confidence

Answer:
The cryogenic Quad Jet modulator consistently delivers reproducible quantitative results not only within the lab but also between labs worldwide. This is achieved because:

  • There are two cold jets. So, eluent from the primary column does not flow into the secondary column by mistake
  • The distance between cold zones is identical in every system worldwide, unlike other systems that require manual adjustment and intervention
  • The modulation is completely computer controlled. This along with the 2 separate cold zones, allows for variable modulation periods in the same analysis, vastly improving separation across the chromatogram
  • In the same way the primary column is temperature controlled in the primary oven, the secondary column is also independently controlled, allowing for total control of the chromatogram along the entire column setup

These four features not only improve separation and control, they are also unique to the LECO QuadJet.

Answer:
By combining comprehensive two-dimensional gas chromatography (GC×GC) with high-speed, high-sensitivity time-of-flight mass spectrometry (TOFMS), LECO's GC×GC-TOFMS can separate and identify the complex mixtures of flavours and fragrances in food samples with detail and precision.

Answer:
Yes! LECO’s GC×GC-TOFMS is an excellent tool for non-intentionally added substances (NIAS) analysis in food safety. It allows for the comprehensive analysis of complex food samples, ensuring the detection and identification of potential contaminants and unwanted substances. For example, LECO’s MOSH/MOAH solution is widely recognised as the most comprehensive and rigorous analyser for mineral oil contamination in food stuffs.

Answer:
LECO’s GC×GC technology utilizes two stages of separation, significantly increasing resolution and analysis power compared to traditional gas chromatography. This allows for the detailed separation and identification of complex mixtures with unparalleled precision.

Answer:
LECO’s TOFMS technology offers excellent sensitivity, speed, and resolution in mass spectrometry. By fragmenting and ionizing analyte molecules and separating the fragments based on their mass-to-charge ratio, LECO's TOFMS enables highly accurate identification and detection of compounds in samples. The system not only records to a computer at high speed, it detects at a rate of 32,000 Hz thus producing a very high level of accuracy.

Answer:
GC×GC-TOFMS enables the analysis of dietary supplements for the presence of non-compliant ingredients, such as animal-derived gelatine, ensuring that the products meet the strict requirements of Halal certification.

Answer:
GC×GC-TOFMS is a valuable tool for monitoring air and soil quality near Islamic sacred sites, identifying pollutants that may pose a risk to their preservation and guiding conservation efforts. As an example, Imperial College London have utilised a LECO Pegasus BT 4D to identify microplastics in the air of London. You can read about it here.

Answer:
LECO’s GC×GC-TOFMS system utilizes Time-of-Flight Mass Spectrometry (TOFMS), which provides high-speed detection of ionized compounds based on their mass-to-charge ratio.

Answer:
LECO provides software for data analysis, enabling compound identification, quantification, and other types of analysis based on the mass spectra obtained from the TOFMS.

Answer:
LECO’s StayClean ion source, a standard feature in every Pegasus BT GC-TOFMS and GC×GC-TOFMS system, flushes neutrals and contaminants continuously. This virtually eliminates the need for routine maintenance, allowing you to spend less time on upkeep and more time on your research.

Answer:
Sample handling is crucial in GC-MS analysis. LECO employs advanced sample handling robots called Autosamplers that can handle samples in three dimensions of space. These robots ensure precise and consistent sample preparation, ranging from simple liquid injections to complex processes like chemical reactions, extractions, and accurate dilutions.

Answer:
The first GC-MS was a GC-TOFMS developed in the 1950s. However, the technique was too powerful for data recording at the time. In the mid-1990s the first GC-TOFMS capable of recording the data for processing was developed by LECO. This breakthrough in fast GC-TOFMS technology allowed researchers and analysts to utilize the capabilities of GC-TOFMS for their analytical needs.

Answer:
By combining two-dimensional separation, robust ionization, and high-speed TOFMS detection, and patented deconvolution algorithms LECO's GC×GC-TOFMS system offers a powerful solution for analysing complex mixtures with enhanced resolution, sensitivity, and separation power.

Answer:
By analysing the chemical composition of materials used in ancient Islamic artifacts, GC×GC-TOFMS assists in determining their authenticity, providing valuable insights into historical and cultural heritage. The chemical composition of such artifacts are extremely complex so utilising multidimensional chromatography techniques with high speed TOFMS, a chemical profile can be created.

Metabolomics presents challenges for both the analytical methods used and the data reduction required to interpret the results. No single analytical technique can be used for complete characterisation of the metabolome, and no metabolome has been completely characterised. However, GC-MS provides an established method to analyse the primary metabolome, whereas LC investigates the secondary and tertiary metabolites.

LECO Solutions for MOSH/MOAH

Whatever your sample preparation workflow requirements are, harness the power of LECO GC×GC & TOF technology to solve the complex challenges of MOSH / MOAH Analysis.

Iron Ores Mining

When the Kaunis Iron Mine opened in Sweden, it was the newest in one of Sweden's biggest industries. The mine contracted with Degerfors Laboratory (D-LAB) for their iron analysis. Before analysis could be run on the samples, however, the ore had to be dried and moisture levels measured.

D-LAB had a problem: their current moisture determination methods used a manual balance that could only handle one sample at a time, requiring a technician's attention every five minutes. The ISO 3087:2020 method used was also a problem, as a single run could take more than 5 hours to complete. The lab turned to LECO for a solution.

Cake for Celebrating 30th Anniversary of LECO CZ

As part of the celebration of LECO's 30th anniversary in 2021, the ribbon was cut on the new LECO office in Plzen, Czech Republic.

The Dumas method has several advantages over the Kjeldahl method: it is much faster, with much lower operating costs, no real safety issues, and no toxic waste produced. However, there is a debate over which of the two main approaches to the Dumas method is better: a vertical or a horizontal combustion furnace. Determined to settle the question on which method is more precise and offers the most advantages, LECO chemists analyzed many sample types in both an FP828 and an FP928.

For more information and a detailed breakdown of the results and a look at more of the samples used in this experiment, read Michael Jakob's article in the September 2021 issue of eFOOD-Lab International.

Microplastics: Seeing the Details with GC×GC

Microplastics are a ubiquitous presence in the world, found from Arctic snow to Antarctic ice and everywhere in between. There are trillions of microplastic particles floating on surface water, and everyone from infants to adults are presumed to be ingesting anywhere from dozens to tens of thousands of these particles every day.

The TGA: Macro and Micro

Thermogravimetric analysis (TGA) first started in the early 20th century, and while the technology has advanced, the basic principles remain the same. With TGA, the rate of change of reactions in the chemical and physical properties of materials as functions of temperature or time is what is used to assess the properties of the sample materials. Most TGA these days is done with either micro TGAs (using milligram-size samples) or macro TGAs (using gram-size samples).

Folded Flight Path®: Ten Years of High Resolution

The first Time-of-Flight (TOF) mass spectrometer was proposed in 1946, and the design has been refined and iterated upon every since.
With an unlimited mass range visible in each spectrum and a high spectral generation speed, the advantages of TOF mass spectrometry were immediately clear. Though the instruments improved, they did eventually hit physical limitations that restricted the resolving power. More work had to be done.

THE FAST GC TECHNOLOGY FORUM

All the tricks of the trade won't be enough if your instruments can't handle the speed. LECO's Pegasus® line is designed to take full advantage of the speed of TOFMS analyses without sacrificing the sensitivity you need, and our StayClean® Ion Source means you never have to slow down to clean out your engine.

 Thermogravimetrically Testing Biomass

So many factors go into the quality and characterisation of plants and biomass, but many thermogravimetric analyses take so much time. Drying, ashing, and weighing multiple samples takes effort and care just to control for atmospheric effects, much less to actually get precise results that can then be used to analyse the quality and structure of the plants. LECO's TGA801 is an automated thermogravimetric analyser designed to take the time out of the testing.

 LECO in Times of COVID-19

The past year with the rise of Covid-19 around the Earth has been a challenge to all of us. See how our European subsidiaries dealt with the pandemic around Europe and how our customer support and other services adapted to these new situations in the different countries.

The start of the years begins with the usual enthusiasm, targets set, goals to achieve and strategy to achieve them. I remember being in Dusseldorf for a managers meeting on March the 3rd. Life was still normal, and the word ’lockdown’ was only ever heard on a Friday when my children were watching Wrestling. We were able to travel, visit restaurants and have a beer without the constraints of the facemasks, social distancing and track and trace apps. Life was normal. Within a month the world changed – lockdowns, stay-at-home, work from home, stay safe.

As the LECO customers adapted to this new way of life due to COVID, so did we. Our sales force worked from home and like never before used this relatively unheard-of platform called Microsoft TEAMS to interact with customers.


“I hear the chimes of ‘TEAMS’
calling me in my sleep now.”

LECO UK Facemasks

Our service team continued to work throughout the pandemic with the new additions to their LECO uniform. LECO face masks and gloves. And of course, let’s not forget the bottles of hand sanitiser. As well as remote selling was used, remote service support came to the forefront. Both sales and service teams adapted to continue the high level of support that has become a custom with LECO.

LECO UK has been able to adapt and continued to support our customers while keeping ourselves and customers safe. Let hope moving into 2021 we can get back to some sort of previous normality. The vaccines are coming and there is a glimmer of light at the end of the tunnel but for the moment we continue with the slogan of Hands – Face – Space.

It has for sure been a challenge even though Sweden have had less restrictions. When crossing borders to Norway, Denmark and Finland our service technicians have sometimes had to take Covid-19 tests before. We have been fortunate, no one in our team have been infected as we know of. We haven’t even been to Iceland since the start of the pandemic. Our service technicians try to go by their own cars to customers, which have meant drives up to 14 hours single way.

On the sales side it has of course been a challenge in other ways. But with ‘Teams’, online demos and Virtual Trade show our sales team have connected with our customers in the best way possible. We only attended one real trade show since the start of the pandemic – LabDays in Copenhagen – but the attendance was of course quite thin…

LabDays Copenhagen 2020

 

Lennart Schwartz, Ph.D, Sales Director Nordic Region, LECO Nordic AB


Since 14th of March of 2020, and the declaration of State of alarm in Spain, Leco Instrumentos started to work in a new different way, adapting to the new scenario of pandemic. All the employees completed a training course regarding the new risk at work and the personal protective equipment for COVID-19:

  • We all learnt about the use of face masks and the way to wash our hands
  • Some employees customised their masks… thanks to their mother’s support!
  • Remote working was the only option in most of cases.
  • Virtual meetings have come to stay.
  • The service team has been active since the first day, working in safe conditions.


Remote Service and Move LECO Spain


So far, everything was normal… But LECO Spain had to face a new challenge – to move to a new office. It was a hard task cleaning the old facilities and open boxes – a lot of boxes. And in times of COVID we had to consider to organise small groups at the office working together. Minimising risks was a priority despite of the fact that we needed to be operative in the new facility in a short time. The collaboration of the Tres Cantos-based employees was essential.

But the result made the effort worthwhile! And the Spanish LECO team is ready for 2021!

 

Leticia García, Commercial Director, Spain & Portugal


German Team Wearing Masks

From the perspective of the German Service Centre, a Corona routine has emerged throughout the past months. Customer demands increased - ever so often our service engineers are only allowed to enter labs after presenting a negative Corona test result. Of course, this requires special logistics in scheduling. In addition, there are different Corona rules the federal states of Germany and abroad, which makes planning much more difficult. But our colleagues adapt, as the pictures show, and as our colleague Manuel Lindemann describes below.

"When the pandemic really took off from March / April 2020, I first noticed a lot of uncertainty among both myself and the customers. There were many questions: What is Corona? What happens if I fall ill? How will this affect my work? Will the customers still let me enter their lab? How will LECO react? Now, almost a year later, there are still some questions left to be answered, but as humans we adapt and get used to the new circumstances – positive and negative.

in the beginning of the pandemic, I remember waiting for hours in 100m-long queues between lorry drivers and other visitors at a company and having to wait for the gatekeeper to let me pass. And there were customers who had their "special" views. From "Corona doesn't exist” to “You don't need the mask here" and "We have an internal lockdown, you can't get in" – it was all there.

After one year many questions remain unanswered, but some questions have already become obsolete. What remained as well, unfortunately, are the waiting times at customers‘ sites. Simply walking in and working on a unit is no longer possible. "Where are you from? Have you had contact with infected people? What does your Corona Warn app say? Do you have any symptoms?” ...And so on. What I've also noticed is that social interaction often gets left behind these days unfortunately – be it a casual conversation or just a gesture that disappears behind the mask. But, hopefully that is to come back soon.

But LECO protect their employees very well and always has an open ear for questions – a solution will be found together. All in all, I think we have organised ourselves very well and will probably make it through the rest of the pandemic."

 

Manuel Lindemann & Thomas Post, LECO Instrumente GmbH Deutschland


After a beginning of year full of prospects and projects, the arrival of Covid-19 took us by surprise. Italy was the first European nation to be massively attacked by the virus, the first cases recorded were in the north of the country, particularly in Lombardy, the region where the headquarters of the LECO branch in Italy are located.

To counter the spread of the virus, the entire country was placed in the "red zone" and operations were greatly reduced to adapt to the new situation.

  • The symposium of world interest on the GC×GC in Riva del Garda, as well as other local events, albeit no less important, have been cancelled
  • We did our meetings online
  • The office staff worked in smart working
  • The technical staff continued to follow their customers both remotely via the telephone and with remote interventions, and in person with the help of masks, gloves, overalls and protective goggles.


The pandemic has led us to cover our faces with masks, but it has not managed to extinguish our enthusiasm and we hope that 2021, together with the vaccine, gives us the opportunity to resume showing our smiles.

 

Rita M. Monfredini, LECO Italy S.R.L.


We’re dealing with the pandemic problem in a similar way, like the rest of the world:

  • Using, masks and gloves
  • Struggling with scheduling sales visits
  • Mostly using ‘Teams’ and mobile phones to contact with each other and with customers…

The Difference between Frankincense and Myrrh

It's that time of year again, when holiday songs play 24/7 on the radio and people start wondering what, exactly, frankincense and myrrh are and why they make good gifts. LECO placed these two oils in a Pegasus BT 4D to see the difference.

Frankincense (from the boswellia tree) and myrrh (from the commiphora tree) are both resins which are commonly used as perfumes and incense and have been for thousands of years. Essential oils extracted from these resins can be analyzed using gas chromatography, which is precisely what the scientists at LECO did.

By extending the analysis to a second dimension using the GC×GC analysis of the Pegasus BT 4D, even more information can be gleaned from the samples extracted from these substances. GC×GC analysis also inherently produces structured chromatograms where chemically similar analytes tend to elute in ordered bands through the GC×GC separation space. This provides context for identification and allows for rapid visual characterization of the compound classes.

 

Chromatogram of Frankincense and Myrrh

 

For a more detailed breakdown of the analysis of these oils and how the GC×GC separation provides a huge advantage in the characterisation and comparison of these samples, fill in the form and check out our application note.

Low-Level Nitrogen Samples in Food Materials

Did you catch our recent article on Food Navigator? Nitrogen content in food materials is necessary to measure when determining the total protein content. This measurement of nitrogen content can be performed using a classical wet chemistry method, but this tends to be a slow and tedious process. The combustion-based Dumas method has gained popularity in recent years as it significantly increases laboratory productivity. Yet when the sample has a low level of nitrogen it can be challenging to analyse. Examples of these hard-to-analyse samples include dry corn starch, NDIN filter bags, nutritional drinks, and beer. How can the combustion method be optimised to accommodate these lower-level nitrogen samples?

Metabolomics presents challenges for both the analytical methods used and the data reduction required to interpret the results. No single analytical technique can be used for complete characterisation of the metabolome, and no metabolome has been completely characterised. However, GC-MS provides an established method to analyse the primary metabolome, whereas LC investigates the secondary and tertiary metabolites.

Cost Effective Soil Analysis with the LECO CHN828

Soil is the material where corn grows. This sounds to be a simple sentence, but keep in mind, that a big part our food is directly or indirectly coming from plants that are sown, grown and harvested in agricultural soil. For modern agriculture especially when including environmental concerns, the chemical analysis delivers very important parameters for a complete characterisation of soil. LECO is the specialist for CNS and moisture/ash analysis in soil, as well as for Carbon species analysis like TOC/TIC or according to EN 17505 TOC400, ROC, ROC900 and TIC 900.

The rise of omics has been a hot topic in our group for the past few years – in part because our own expertise aligns somewhat with the needs of these fields. Metabolomics is then particularly challenging for the separation science community, demanding the application of high-end iterations of various techniques, including LC, GC, MS, and NMR. In fact, when it comes to metabolomics, most analytical tools have a “seat at the technique table” – after all, multimodality is the only way to make sense of such high sample complexity.

An Article by Pierre-Hugues Stefanuto, Delphine Zanella, and Jean-François Focant

From cancer to diabetes to the recent rise of COVID-19, we will all likely come face-to-face with a threat to our health. Contemporary medicine has ever-improving tools to identify and combat diseases, but there are gaps – in speed, in invasiveness, in coverage, in access, and in accuracy. Can we do better? And how can we ensure that new approaches provide the same level of diagnostic potential as those currently in service?

Jane Hill, Associate Professor of Engineering, and Billy Boyle, CEO of Owlstone Medical, explain how their research in the area of breath analysis is opening new diagnostic doors.
