Purgeable Volatile Organic Compounds by GC–MS Using Zebron™ ZB-624PLUS™ GC Columns

Researchers from Austria, Greece, and Italy conducted a study to analyze volatile organic compounds (VOCs) present in Irish and Scotch whiskys using solid-phase microextraction (SPME) Arrow with comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC–MS) to examine the organoleptic characteristics that influence the taste of spirits.

A study has used gas chromatography coupled to a time-of-flight mass spectrometer to build an electron ionization mass spectra database of more than 250 chemicals classified as either volatile or semi-volatile compounds. An additional, confirmatory layer of liquid chromatography–mass spectrometry analysis was subsequently performed.

Limited toxicokinetic and toxicologic information is available about a diverse set of per- and polyfluoroalkyl substances (PFAS), but methods based on gas chromatography–tandem mass spectrometry (GC–MS/MS) can help unravel some of the mystery.

Recent advances in green chemistry have made multivariate experimental design popular in sample preparation development. This approach helps reduce the number of measurements and data for evaluation and can be useful for method development in gas chromatography.

Messina Institute of Technology scientists used gas chromatography–mass spectrometry (GC–MS) was used to profile illegal samples of Cannabis sativa L.

In this article, the authors describe a simple workflow to develop a GC×GC method for a specific sample upon initial use, with the aim of decreasing the time to accomplish functional workflows for new users.
