Incognito lectures on the importance of knowing the fundamentals of your GC methods.

This article describes analyte adsorption in vials with reduced surface activity compared to those made from standard borosilicate glass.

This article presents GC–GC(qMSMS) data on the analysis and quantitation of polychlorinated biphenyls (PCBs) in a complex matrix (fly ash). Calibration curves were recorded between 0.1 pg and 100 pg.

Scientists from San Pablo CEU University (Madrid, Spain) have developed a non-targeted global fingerprinting approach for lung tissue samples by performing three analytical methods ? liquid chromatography coupled to mass spectrometry (LC–MS), gas chromatography coupled to MS (GC?MS), and capillary electrophoresis coupled to MS (CE–MS). Published in the journal Analytical Chemistry, the study details the development and validation of the multi-platform approach using 20 mg of lung tissue.1

Donna Nelson of the University of Oklahoma, USA, and scientific advisor to the hit television show Breaking Bad spoke to The Column about her research in academia, as well as her role on the show.

Scientists from the Duke Medical Center (North Carolina, USA) and the Bascom Palmer Eye Institute at the University of Miami (Florida, USA) have performed liquid chromatography coupled to mass spectrometry (LC?MS) to identify a new diagnostic marker of Retinitis pigmentosa (RP) in patient urine samples.1 RP is a disease of the eye that causes retina degradation and can result in blindness. Often inherited, it has multiple contributing genetic mutations and there is no treatment available.

The 20th International Symposium on Electro- and Liquid-Phase Separation Techniques (ITP2013) was held for the first time in Spain (Puerto de la Cruz, Tenerife, Canary Islands) on 6?9 October 2013.
