Gas Chromatography

To fully grasp the concepts of retention and selectivity of GC stationary phases, one must first understand the fundamental intermolecular interactions that lead to retention. This article discusses the most dominant of those interactions –...

Here, we tackle another potential problem of hot split injection: sample decomposition. Decomposition changes the nature of components in the original sample, affecting the “recovery” of target compounds. This in turn introduces errors in analytical...

This technical article discusses the process of hot split injections and the sources of discrimination, which are one of the potential downsides of this technique.

This article will discuss split injections with a hot split/splitless inlet. This is the most popular inlet and sampling mode for capillary GC. The focus will be on the basic concepts and flow paths. Later articles will cover liner choice,...

This technical article provides a general overview of the purpose of GC columns, key processes involved and a description of differences between them.

Would you like to learn about a new extraction technique that provides a valuable extension to regular solid-phase microextraction? If so, this on-demand webinar will teach you all about the benefits of thin film solid-phase microextraction...

Do you need to increase productivity and decrease downtime in your laboratory? This on-demand webinar introduces Agilent’s new suite of intelligent gas chromatographs that will help you reach this goal.

Shimadzu has released the Nexis SCD-2030 sulfur chemiluminescence detection system consisting of a Nexis GC-2030 high-performance GC and the newly developed SCD-2030 sulfur chemiluminescence detector. With this product, Shimadzu serves a growing...

Today's laboratories are being asked to do more everyday – more samples run, more data acquired, more chemical information processed, and more results achieved – all in less time, and for less money.A smart investment for any laboratory looking to...

This presentation from LECO will help you understand the differences between the use of GC and GCxGC with high performance TOFMS and the benefits of using GCxGC for determining terpene profiles of cannabis strains.

The LECO Pegasus^® BT has been designed to perform qualitative or quantitative analysis of knowns and unknowns. The benchtop instrument combines new, compact time-of-flight mass spectrometer hardware with powerful ChromaTOF brand software, giving...

Struggling with too much GC column maintenance or troubleshooting? Are you adjusting too many retention times after changing your column? Tired of venting your mass spec to trim the column yet again? If so this helpful GC-focused webinar is for you....

Want to know what extending the upper temperatures limits of your WAX columns will do for your run times and applications? Watch this presentation to find out...

Separation Science, in collaboration with Peak Scientific, is pleased to offer an on-demand presentation addressing potential alternatives to helium as a carrier gas in GC analysis. 

Helium has been the preferred carrier gas for GC applications for...
