GCxGC Data Handling: ChromaTOF Tile

June 9, 2023

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.

Just-in-Time Derivatization

April 7, 2023

For many of us, COVID-19 changed the way we work. It changed the way we communicate, gather, and network. Large tradeshows like Pittcon moved virtual or shuttered their doors entirely, and sometimes, that wasn't the worst thing. Less time traveling meant more time available in the lab, attending to your instruments. But after three years of this, it's time to step away from your instruments and let automation take over.

Food, Flavor, and Aroma eBook with Separation Science

February 24, 2023

Few things in the world bring people together like food. Flavor and aroma are often central pillars of a good time. Whether it’s developing a meat substitute or characterizing the subtle intricacies of liquor, the study of food, flavor, and aromas is critical to so many industries that touch everyone around the world.

Greener Peppers: A Sustainable Food Analysis Method

February 3, 2023

The analysis of peppers for flavor profiles and food volatiles is not new. With a wide array of varieties, peppers find uses in not just food markets, but also pharmaceutical and cosmetic industries. Analyzing peppers isn't new. Finding ways to increase the sustainability and "green" qualities of those analyses, however, is an ongoing challenge, and one that Micaela Galletta, Mariosimone Zoccali, Donato Creti, Luigi Mondello, and Peter Q. Tranchida tackled in a recent study published in Green Analytical Chemistry.

Detailed Analysis: Easy Whisky Characterization

January 13, 2023

How do you handle the analysis and characterization of a complex sample like whisky*? In a recent interview with eFood Lab International, Dr. Geraint (Taff) Morgan of the Applied Science & Technology Group at the Open University, UK, says a 1D quadrupole GC-MS is sufficient for routine analysis, but when he really wants to dig into the non-target analysis of a complex sample, he turns to GC-TOFMS and GCxGC-TOFMS, such as that employed by the LECO Pegasus® BT 4D.

Expand your Toolbox with the HRT+

July 29, 2022

Gas chromatography-mass spectrometry (GC-MS) has long been an invaluable tool in a chemist's belt. With its ability to tease apart the compounds in a sample, identifying even trace analytes, it is able to perform specific tests and pinpoint what, exactly, is in the material being analyzed. But what can you do when GC-MS isn't enough?
