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: Fungicide residue concentration found by GC evaluation

Grapes tend to suffer from a number of fungal diseases, so are often treated with fungicides, which can leave behind potentially harmful residues. Scientists from Guizhou University in China have developed a new GC-MS/MS method that can simultaneously assay the residues of two fungicides, boscalid and fludioxonil, in grapes and soil.

Phthalate esters are widespread environmental contaminants and there is concern about their possible health effects so accurate methods to measure their plasma concentrations are needed. Scientists from Iran have used dispersive liquid–liquid microextraction (DLLME) and GC-MS to measure the levels of four common phthalates.

The chemodiversity of gorgonian alkaloids was investigated by applying a fast and effective protocol combining extraction and derivatization using small-scale tissue samples and GC/MS analysis.

There is a need to be able to distinguish smokers from non-smokers by testing chemicals in their breath, but it is hard to find appropriate marker compounds. Scientists from the Institute of Microelectronics and Microsystems in Italy, have developed a new method of examining the volatile organic compounds (VOCs) in smokers’ breath using GC-MS and statistical tests.
