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.

The introduction of comprehensive two-dimensional gas chromatography (GC×GC) to the sample screening toolbox has substantially increased the ability to comprehensively characterize complex mixtures. However, for many gas chromatography (GC) users, the thought of having to learn to develop methods on a new technology is daunting. Developing a basic GC×GC method for most (nonspecialized) applications can be accomplished in minimal time and effort given parameter suggestions and ranges to target analytes in a sample of interest. In this article, the authors work 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.

In this edition of The LCGC Blog, Katelynn Perrault and James Harynuk discuss the technological needs one faces when setting up a workstation for chromatography data analysis.

The 15th Multidimensional Chromatography Workshop is a free event involving keynote and contributed presentations, a poster session, and discussion groups on all multidimensional techniques, and will be held in-person on the campus of California State University, Los Angeles, from January 10 to 12, 2024.

This past spring, we convened a panel of six phenomenal separation scientists, where they gave their best advice for separation scientists, newcomers and veterans alike.

GC×GC is now a well-established technique, but it is still underutilized in many settings.

This article is intended to begin demystifying GC×GC by presenting a simple explanation of how it works and its major benefits.

Comprehensive two-dimensional gas chromatography (GC×GC) is becoming increasingly popular, but is still not used as commonly as it could be. That likely means that the technique is still not widely understood. This article is intended to begin demystifying GC×GC by presenting a simple explanation of how it works and its major benefits.

Empowering the next generation of female separation scientists is crucial to helping them realize their potential in advancing the separation science field.

This time of year tends to serve as a reminder that while women may be entering more degrees and careers in science than ever before, there is still a need to advocate for gender parity in many sectors.

The 13th Multidimensional Chromatography Workshop is a free virtual event involving keynote presentations, contributed presentations, and discussion groups, and is happening virtually on 31 January–2 February 2022.

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.

As our academic year comes to end, I always take time to reflect on what I have learned in the past year. As an assistant professor in Forensic Sciences and Chemistry at Chaminade University of Honolulu, I take the opportunity to review my courses regularly and implement new tools. Some of them will be successful and others will not.
