This study illustrates the importance of column selection during GC method development.

Profiling Free Naphthenic Acids in Produced Water Using Gas Chromatography Coupled to High-Resolution Accurate Mass–Mass Spectrometry (GC–HRAM-MS)

In 2015, the American Chemical Society’s Committee on Professional Training added a requirement to the ACS degree certification program that undergraduates learn about macromolecules, supramolecular aggregates, and nanomaterials (MSN). This requirement can be met by a specialized course in these topics, but many programs are also choosing the distribute these topics across the curriculum.

The LCGC Blog: Polymers, Macromolecules, and Nanomaterials in the Separation Science Curriculum

HS-SPME-GC–MS was combined with OPLS-DA data analysis to tentatively identify eight chemical markers to differentiate the geographical origins of cigar leaf samples.

Headspace Solid-Phase Microextraction Coupled with Gas Chromatography–Mass Spectrometry (HS-SPME-GC–MS) for the Characterization of Cigar Leaves

Decomposing animal tissue releases volatile organic compounds (VOCs), of interest in forensic science. We describe the use of GC×GC–qMS/FID retrofitted with a reverse fill/flush (RFF) flow modulator for analyzing these VOCs in a tropical climate.

Investigating Decomposition Odor in a Tropical Climate by Comprehensive Two-Dimensional Gas Chromatography (GC×GC) Coupled with Mass Spectrometry (MS) and Flame Ionization Detection (FID)

Pyrolysis–gas chromatography–mass spectrometry has advantages for the analysis of environmental microplastic samples compared to other leading analytical methods, including spectroscopic techniques.

Identification of Microplastics in Environmental Monitoring Using Pyrolysis–GC–MS Analysis

This article looks at the benefits of combining dynamic headspace sampling (DHS) with capillary GC–TOF-MS as a tool for untargeted analysis of aroma compounds in food and beverages. Applications for the analysis of strawberry yoghurt, chocolate, and red wine are described.

High Analytical Performance for Untargeted Aroma Profiling by Combining Dynamic Headspace Sampling, Capillary Gas Chromatography and Time‐of‐Flight Mass Spectrometry

“GC Connections” presents the column’s annual review of new developments in the field of gas chromatography seen at Pittcon and other venues in the past 12 months.


New Gas Chromatography (GC) Products for 2020–2021

A novel analysis technique has been developed for the determination of microplastics (MPs) in complex environmental samples using thermal extraction desorption gas chromatography–mass spectrometry (TED-GC–MS).

Determination of Microplastic Mass Content by Thermal Extraction Desorption Gas Chromatography–Mass Spectrometry

Mass spectrometry (MS) is the most powerful detector available for gas chromatography (GC). This article reviews the fundamentals of MS/MS and how they relate to MS as a detector for GC, then examines scenarios where use of GC–MS/MS can solve complex problems.


Flying High with Sensitivity and Selectivity:- GC–MS to GC–MS/MS

By moving from GC–MS to GC–MS/MS, you can have both universal and selective detection along with low detection limits. Here’s how it works.
