GC @ separationsNOW

The Gas Chromatography channel covers all techniques used for the separation of gases, in addition to the supercritical phase.

This includes multidimensional techniques (e.g. GCxGC) and hyphenated techniques (e.g. GC-MS).

Last Month's Most Accessed Feature: GC-MS defeats the doping steroid cheats

Doping with anabolic steroids remains a significant problem in many sports, particularly since identification of these compounds and many of their metabolites is hampered by their relatively short lifetimes in the body. Scientists from Ghent University in Belgium used GC-MS with chemical ionisation to detect novel long-lived metabolites from the anabolic steroids oxymesterone and mesterolone.

Routine gas chromatographic analysis not only has to fulfill the specific conditions given by the respective target samples; it also has to cope with additional economically and ecologically driven demands. Reduced cost per sample and high-sample throughput needs affect basic decisions like gas selections and analysis runtimes. All of this ideally without compromising the performance of the gas chromatograph.

The organophosphate insecticide ethion can be harmful to human health so residue levels on food crops need to be monitored. Researchers from the Sher-e-Kashmir University of Agricultural Sciences (Srinagar, India) used GC with an electron capture detector (ECD) to investigate ethion residue levels on cucumbers.

Thermal desorption GC is often used for the analysis of volatile compounds, but the accurate introduction of reference standards can be difficult to achieve. Researchers from the University of Leuven, Belgium, investigated the losses that can occur with offline liquid calibration (OLC) methods, also examining inline liquid calibration (ILC).

Headspace SPME-GC/MS and chemometric analysis have been used to analyse VOCs released from Ganoderma boninense cultures and infected oil palm wood to predict the onset of Ganoderma disease and help to study plant–pathogen interactions.
