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.

The fungicide dimethachlon is widely used on rice plants in China, despite its relatively high level of kidney toxicity. Scientists from the Guizhou University (Guiyang, China) developed a new GC method using electron capture detection (ECD) to detect dimethachlon residues in paddy soil, rice straw, rice husks and rice grains.

Two-dimensional GC, where the output of one column is put through another, is a powerful technique that is being increasingly applied to complex mixtures of metabolites. Scientists from the Sharif University of Technology (Tehran) and IDAEA-CSIC (a government institute in Barcelona) compared the effectiveness of ordinary GC-MS with that of two dimensional GC plus time-of-flight MS for metabolite detection in Daphnia (water fleas), employing chemometric techniques to manipulate the data.
