Retention Times of 209 PCB Congeners Using GCxGC-TOFMS - LECO apps note

At the 2024 Pittcon Conference, Elizabeth Humston-Fulmer of LECO Corporation presented an improved workflow which uses two-dimensional gas chromatography (GCxGC) with dual time of flight (TOF) MS/FID detection. Shortly after Pittcon, Humston-Fulmer discussed this analytical method with us.

In this edition of “Inside the Laboratory,” Katelynn Perrault Uptmor, PhD, an assistant professor of chemistry at the College of William and Mary, discusses her group’s current research endeavors, including using complex comparative data obtained from chemical analysis to understand and solve challenges in forensic science and other life science applications.

This study explores the feasibility of using human skin volatile organic compounds (VOCs) analyzed through comprehensive gas chromatography–time of flight–mass spectrometry (GCxGC-TOF-MS) and chemometric techniques, to potentially serve as biomarkers for tuberculosis diagnosis.

LCGC spoke to Leandro Wang Hantao from the University of Campinas in São Paulo, Brazil, about his work investigating the influence of ion management parameters on the data produced by comprehensive gas chromatography–high-resolution mass spectrometry (GC×GC–HRMS) equipped with a fourier transform-orbital ion trap mass analyzer, and his investigation into employing channel occlusion for sample preparation in untargeted analysis in petroleomics.
