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.

A variety of aroma compounds are found in e-cigarettes, but little information is available about their prevalence and potential inhalation toxicity. A team of researchers from the University of Innsbruck and the Austrian Drug Screening Institute used GC/MS to quantify the levels of various aroma compounds in commercial e-cigarette liquids, while also looking at the compounds’ effects on human cells.

Organophosphate esters (OPEs) are widely used as flame retardants and plasticisers, but can have adverse environmental effects in bodies of water. Scientists from the Limeira campus of the University of Campinas (Brazil) developed a method for quantifying low levels of organophosphate esters in river water using SPE and GC/MS with a programmable temperature vaporiser (PTV) inlet.

Orbitrap instruments can be used for GC–MS, but there may be significant differences between the electron ionisation (EI) spectra produced with this detector and conventional EI spectra. A team from the University of Technology of Compiègne (France) examined the differences between GC/MS Orbitrap (EI) spectra and conventional GC/MS EI using fatty acid methyl esters.
