Elemental Analysis, Separation Science, And Metallography News By LECO

We're thrilled to share some exciting news from our European Application and Training Center (EATC) in Berlin! Recently, we've enhanced our capabilities with the installation of the latest model of LECO's High Resolution Mass Spectrometer, the Pegasus HRT⁺4D.

Embark on a scientific odyssey into the captivating world of aroma analysis as we delve into the intricate bouquet of 'Cacciatori di Briciole' (Breadcrust Hunters) beer. Through meticulous analysis conducted by esteemed scientists, we explore the transformative power of sustainable brewing practices.

Perfect and easy analysis for solid and liquid products.

Protein is one of the most significant nutrient components in milk products. The accurate and precise determination of protein not only plays a role in the characterization of nutritional or dietary value of milk products but is also the key to determining the economic value of these materials. Protein in milk products is most commonly calculated using the measured total nitrogen content in the sample and a multiplier or conversion factor (typically 6.38). Nitrogen determination is performed using either the classical wet chemical method (Kjeldahl), or a combustion method (Dumas).

As the concern for global warming has increased over the years, ways to sequester carbon has been top-of-mind for many scientists and researchers. Capturing atmospheric carbon in the form of carbon dioxide, converting it, and storing it in soil would not only help the overall environment, but it could help farmers grow better crops as well.

And the award goes to…

Professor John Langley!

He is a beacon of excellence in the realm of separation science. We are thrilled to announce that Professor Langley has been honoured with the prestigious 2024 Silver Jubilee Medal by The Chromatographic Society!

Elevate your expertise in analytical chemistry and food safety with a hands-on demonstration of the state-of-the-art GC×GC-TOFMS/FID workflow for MOSH/MOAH analysis.

While time-of-flight mass spectrometry (TOFMS) was first proposed in 1946, the technology simply didn't exist to allow for fast enough processing speeds to make it widely viable until 1995, when the Fast Chromatographic Detector was debuted at Pittcon. This group went on to join LECO and create the world's first commercial GC-TOFMS, the PEGASUS^®, in 1997. Ever since then, technological capabilities have exploded. One-dimensional GC-TOFMS and multi-dimensional GCxGC-TOFMS are powerful and provide rich and highly informative data. If you have a number of samples to study, the volume of data produced might seem overwhelming. However, LECO's data analysis add-ons for ChromaTOF brand software, ChromaTOF Tile and ChromaTOF Sync, have once again pushed GC-TOFMS capabilities beyond what was previously feasible.

Unlike the detailed list of nutritional requirements for human food, pet food in North America must only report on four main values in their Guaranteed Analysis on the label: protein, fat, fiber, and moisture. Additional nutrients must be included if they are called out specifically on the label, but manufacturers can also voluntarily add more nutrients to provide consumers with more information or further demonstrate the nutritional value of their products. One voluntary "nutrient" that shows up with surprising frequency in these lists is actually "Ash". But ash in the analysis doesn't actually mean ash is in the food. Rather, it explains the process by which mineral content is determined.

While plant-based proteins have been part of humanity's diet for centuries, it wasn't until the advent of the original textured vegetable protein (TVP) in the 1960s that it started becoming a viable replacement for animal-based protein sources in more mainstream diets. The first commercially available plant-based proteins would not be mistaken for animal-based protein sources and were largely of interest only to vegans, vegetarians, and pescatarians. 

The world of GC-MS applications is constantly expanding, growing into novel applications and improving classical uses. To celebrate the advancements of this powerful technology, LECO and The Analytical Scientist created an eBook that takes a look at some of the emerging uses of GC-MS. From measuring volcanic emissions to predict eruptions to developing the ultimate untargeted technique with GCxGC-MS, these articles explore a variety of topics.
