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: Zombie drug identification solved by cold ionisation

Regulatory agencies are faced with an ever-increasing number of synthetic cannabinoids, many of which are structurally similar to one another, making their identification a challenge. Scientists from the Hebrew University of Jerusalem and the Division of Identification and Forensic Science of the Israeli police have developed a cold electron ionisation (EI) method to give improved differentiation in the GC-MS of synthetic cannabinoids.

Polychlorodibenzo-p-dioxins (PCDDs) and the related polychlorodibenzofurans (PCDFs) are toxic, persistent organic pollutants, but the current official separation methods for the various congeners are lengthy. Scientists from the Institute of Atmospheric Pollution Research in Rome developed a new GC-MS/MS method using hydrogen as the carrier gas rather than helium.

Opioid pharmaceuticals can have serious side-effects, such as irregular heart rhythms, so it is necessary to be able to measure their concentrations in the blood. Scientists from the University of Buenos Aires used solid-phase extraction, together with GC-MS with selected ion monitoring (SIM), to measure the levels of three synthetic opioids and two of their metabolites.
