Accommodate Lower-Level Nitrogen Samples in Food Materials with an Optimised Combustion Method

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?

"Determination of Pesticides in Tomato Products by GC×GC-TOFMS" – LECO in colaboration with Separation Science

Find out how the use of Comprehensive Two-Dimensional Gas Chromatography (GC×GC) with Time-of-Flight Mass Spectrometry (TOF-MS) demonstrates excellent matrix-analyte and analyte-analyte separation quality of a high number of target pesticides, at high sensitivity.

The LECO Pegasus BT 4D was used to develop a robust and straightforward quantification workflow adhering to SANTE requirements.

Cost Effective Primary Moisture Analysis for Dairy Products

An accurate determination of moisture content in milk products provides important information related to the food quality and safety (texture, taste, microbial stability). Moisture is also a key variable used to calculate a product’s purity, yield, and /or resulting constituent analysis on a dry basis.

The TGM800 provides the user with flexible method settings, automation, and hardware capabilities that maximises moisture determination efficiency, productivity, and analytical performance. This is accomplished while offering the ability to meet the primary loss-on-drying method requirements for sample.

"The detection of honey bee diseases through monitoring shifts in volatile profiles" by Maggie Gill – Keele University, UK

header blogpost eseminar 1440x390px

Today, 20th May, is UN World Honey Bee Day. The honey bee is an important pollinator species that contributes an estimated $15 billion a year to the US economy through crop pollination and £690 million to the UK economy. Honey bees are also important wild pollinators, and play a key role in maintaining biodiversity and ecosystem services in many ecosystems.

e-Food Lab International // Interview with Ralf Löscher

Ralf Löscher speaks about the latest technologies, as well as many years experience LECO has in the field of TOFMS instrumentation. The special focus of this interview refers to the food industry and the special benefits LECO offers to this market.

“In the field of chromatographic separation science technology, LECO offers GC coupled to time-of-flight (TOF) mass spectrometry (MS). This includes one-dimensional as well as two-dimensional chromatography (GC×GC), which increases chromatographic resolution and sensitivity. In addition, our latest technology is competitively priced in relation to triple quadrupole alternatives. Furthermore, GC-TOF-MS technology is basically unbeatable for the analysis of residues in complex matrices such as teas, spices, oily products, but also baby food.“
