Directions in Flow-Modulated GCxGC at LECO

Wednesday, May 31, 1:00 pm

Join LECO as we discuss our journey in flow modulation. Hear about some recent hardware and software developments that promise to simplify your GCxGC workflows. We'll provide some simple steps for method development with Reverse Fill Flush (RFF) that shows GCxGC does not need to be complex.

A sampling of real-world application results in Aroma and Petroleum labs will demonstrate to you how our commitment to research in GCxGC technologies can provide you with both innovative hardware and software solutions that will save you time and effort in your day-to-day work! Be the first to learn about the latest developments from LECO's Research and Development teams.

P07: Pesticide Analysis Using GCxGC-TOFMS & Hydrogen Carrier Gas—A Proof of Concept Study

The analysis of pesticides in food is complex due to the presence of interfering matrix materials. An approach that uses comprehensive two-dimensional gas chromatography coupled to Time-of-Flight mass spectrometry allows for better resolution and detection of pesticides. Due to helium supply issues, hydrogen is being explored as an alternative carrier gas. A proof-of-concept study showed that hydrogen and helium gave similar results in terms of mass spectral fragmentation, sensitivity, dynamic range, and chromatographic resolution.

T03-3: Analysis of Microplastics and their Absorbed Matrix Constituents using Thermal Desorption and Pyrolysis with GCxGC HRT TOF-MS

Plastic waste is a significant concern due to its environmental distribution and health risks associated with chronic exposure to microplastics and adsorbed pollutants. This study aimed to identify microplastics and adsorbed pollutants in the environment using an analysis method involving thermal desorption, pyrolysis, and comprehensive two-dimensional gas chromatography. The method identified multiple polymers and hazardous compounds such as polyaromatic hydrocarbons.

T05-4: Non-Target Characterization of Complex Fragrance Samples with GCxGC MS/FID

This study aimed to improve the characterization of fragrance ingredients using a GCxGC-TOFMS/FID instrument that provides both identification and relative quantification in a single injection, eliminating the need for two separate analyses. The prototype instrument used a reverse fill flush modulator, controlled splitter, and novel algorithms that align MS and FID peaks to ensure reliable analyte identifications and quantifications from single injections. GCxGC was crucial for separating analytes that co-eluted with a 1D separation.
