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 water absorption capacity of flour is an important characteristic that is normally measured by filtration techniques, which can be awkward to use. Scientists from the South China University of Technology (Guangzhou, China) and the Health Supervision Bureau of Liaoning Province (Shenyang, China) developed a novel method of determining the water absorption capacity of wheat flour using headspace GC technology and a thermal conductivity detector (TCD).

Semifluorinated alkanes are used in eye treatments and also as a component of ski wax, the latter use giving rise to concern about possible pollution. Researchers from the University of Münster and the Leibniz Institute for Analytical Sciences, Dortmund (both in Germany) used GC-MS with dielectric barrier discharge ionisation (DBDI), an atmospheric pressure plasma method, to detect a range of semifluorinated alkanes at low levels.

Six new synthetic cathinones that have not yet appeared in any Swedish drug seizures have been synthesized and used with 42 known cathinones to show that a combination of GC/MS and GC-FTIR is required for successful differentiation.
