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.
Finding the sources of off-flavors is easier than ever with LECO GC-MS technology. Quantify and screen samples with a single injection using LECO two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC TOFMS).
Characterize natural fragrances; matrix and unravel complex essential oils. Identify taints and off-flavors to allow the improvement of quality and profitability. See specific examples with our app notes and webinars to learn how LECO's GC and GC×GC technology can empower your laboratory, or get detailed information about LECO's instruments for sensory, flavor, and fragrance analysis.

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.
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.

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 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.
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).
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.
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.
Automated moisture or moisture/ash determination with a primary loss on drying method for replacing the slow labor intensive, manual air oven method is ideal for most applications in the foods, feeds, and milling products industry. LECO‘s cutting-edge thermal gravimetric analysers, TGM800 and TGA801, are industry leaders in every field and run simultaneously for 10 up to 38 samples! Flexible method settings, automation, and hardware capabilities deliver an automated analysis process while requiring only the manual measurement of the initial sample mass, for maximum productivity in your lab.
LECO instruments offer piece of mind for energy companies validating for quality and compliance by measuring for moisture, ash, volatile content, and loss-on-ignition as well as determination of gross calorific value of various organic materials.
Simple entering of your samples into macro crucibles, easy and convenient, no need for touching the sample after starting the instrument.

Our latest online presentations for MOSH / MOAH Analysis are now available as an On-Demand session. With these fundamentals you will learn all the ins and outs on the LC–GC coupling, GC×GC and Time-of-Flight MS to be able to determine MOSH and MOAH in food products.
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.
Our latest Online Workshop is now available as an On-Demand session. In this workshop the LECO Inorganic product line together with interesting applicational examples is presented. CHNOS analysis of steel, semiconductors, inorganic materials, powder metals and others are discussed. The theoretical lectures are followed by a practical demo where the instruments are demonstrated and some typical samples are analysed. A questions and answers session finalises the workshop.

Total sulfur value is an important characterisation measurement for coal, coke, fuel materials, and a wide variety of other organic materials. It is considered to be part of the ultimate analysis parameters (determination of carbon, hydrogen, nitrogen, sulfur, and ash with oxygen calculation by difference). The total sulfur value is a primary parameter used for assessing the quality of a fuel, calculating coal and coke preparation and cleaning processes, and the emissions potential of the fuel. The SC832 Series will bring productivity, precision, and progress to your lab when determining the sulfur and carbon content of your samples.

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.
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…
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:
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
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."

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 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.

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.
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.

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.
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.

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.
