Professor Kieran N. Kilcawley of Teagasc Food Research Centre and of University College Cork and his colleagues are using gas chromatographic (GC) techniques to explore how to analyze the quality and taste of Irish whiskeys through congener profiles.

Multiple headspace extraction (MHE) can be readily implemented with automated headspace-selected ion flow tube mass spectrometry (SIFT-MS).

This article demonstrates how sorptive extraction is a highly efficient technique for the VOC profiling of honey samples.

Small modifications to the way measurements are approached can enable reductions in the waste generated and carbon dioxide produced during an analysis.

The 27th International Symposium on Separation Sciences (ISSS 2023) will be held 24–27 September 2023 in Cluj-Napoca, Romania. Here’s a sneak preview of what attendees can look forwards to.

Pop quiz—can you define resolution? Would you be surprised at the number of correct answers? Which one is the best for chromatographers? In this LCGC Blog, we look at the various ways resolution can be interpreted scientifically.

Optimal reaction conditions for the desired deethylation were found to be mild, using only water and oxygen at or close to ambient temperatures.

Recent developments in GC×GC that make it more amenable for routine use are discussed.

On Thursday, September 28, 2023, the Chromatographic Society (ChromSoc) will hold a meeting focused on gas chromatography in the Science and Industry Museum, in Manchester, UK.

As part of the upcoming Recent Advances in Gas Chromatography meeting, Laura McGregor of SepSolve will discuss how workflows for comparing 1D and 2D GC–MS chromatograms can be automated.

As part of the upcoming Recent Advances in Gas Chromatography meeting, Paul O'Nion of RSSL will provide his perspective on different elements in the periodic table.

As part of the upcoming Recent Advances in Gas Chromatography meeting, Nicholas Morley will look at how two-dimensional gas chromatography-time-of-flight-mass spectrometry analyzes pharmaceutical packaging.

Two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC/TOF-MS) and gas chromatography–time-of-flight mass spectrometry (GC-TOF-MS), two different gas chromatography techniques, will have their procedures and uses compared at the Science and Industry Museum, in Manchester, UK.

Researchers in China studied a new process for measuring aberrant metabolites.

Studies published over the last five years have focused on fully or semi-automated approaches and their applications in extraction of both organic and inorganic pollutants, while modern robotic tools and 3D printing are starting to make impacts.

Microfluidic devices are considered ideal for fabricating portable diagnostic equipment for point-of-care testing, but substrates more environmentally friendly than glass or plastics are attracting interest.

What critical components can help to resolve the separation challenges related to pesticides analysis in food?

HRMS is widely used in chromatography for analyzing complex mixtures. However, chromatographers should take note of the exponentially larger data set that HRMS provides before deciding whether to use the technique for the analysis they are conducting.

We offer troubleshooting tips for various gas chromatography (GC) detectors, as well as provide an overview of the different options chromatographers have when using a GC detector.

A new approach based on post-column in situ hydrogenolysis, and flame ionization was used here to improve characterization of volatile aldehydes. We review and describe that approach here.

What can chiral capillary GC do for you? The answer lies in what analysis one is attempting to accomplish. Here, we discuss the utility of chiral capillary GC and where the technique is most valuable, focusing on three application areas in particular.

A chronological examination of GC is presented here, with a look at where the technique is heading and how it can be used to advance environmental sustainability.

Giorgia Purcaro of the University of Liège discusses the advantages offered by the liquid chromatography–comprehensive multidimensional gas chromatography time-of-flight mass spectrometer/flame ionization detector (LC–GCxGC–TOF-MS/FID) method in the analysis of mineral oil.

This instalment explores the challenges involved in detecting the effluent from a capillary gas chromatographic column and summarizes the many detector options.
