TOP STORY
The direct aqueous injection of ethylene glycol is challenging because it can be difficult to attain reproducibility and good peak shape. The large expansion volume of water can cause backflash, carryover can cause inconsistent results, and excess water can extinguish the flame ionization detection (FID) flame. This article describes a robust approach to analyze glycols in aqueous samples, which reduces downtime and maintains sensitivity. read more

Features
I recently visited a laboratory where the working culture was different to many (perhaps any) that I've ever encountered. It made me reflect on the laboratories that I've worked in, and what makes a good working environment for the rather serious matter of high-quality analytical measurement. read more
This article highlights three events that require new method development to meet various detection needs, ranging from the detection of pesticides such as fipronil and glyphosate, to the detection and quantification of fat-soluble vitamins. read more

News
Researchers from the Université de Pau et des Pays de l'Adour, in France, have developed a large volume injection method using a programmed temperature vaporization (PTV) injector for the simultaneous determination of mercury, tin, and lead at ultra-trace levels in natural waters using GC–ICP-MS. read more
