Inside the Laboratory: The Nontargeted Separations Laboratory at the College of William & Mary
March 25th 2024In 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.
Using Multidimensional GC Coupled to TOF-MS For the Detection of Tuberculosis-Associated Compounds
March 22nd 2024This 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.
Untargeted Analysis in Petroleomics
December 1st 2023LCGC 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.
