Determining the Water Content of Liquid Samples Using Iconic Liquid-based Capillary GC
Developing versatile, rapid, and accurate analytical techniques for the detection and quantification of water in a variety of materials remains an important and ubiquitous analytical problem. This article describes an effective and sensitive ionic liquid (IL)-based capillary gas chromatography (GC) method with thermal conductivity detection (TCD) to determine the water content in liquid samples.

How cells survive, replicate and maintain genome integrity in high NaCl concentrations has long puzzled scientists. A group of US scientists has conducted a series of experiments to determine how this occurs and discovered that cells are actually protected from these conditions by the ?gene deserts?, the 40% of the genome that are thought to serve no purpose.
Event news summary
Detection, analysis, and characterization of low-abundant metabolites remain an unresolved problem in metabolic studies. In this study, we report a novel approach to address this challenge. The current methodology is derived from the predictive multiple reaction monitoring (pMRM) mode available on triple-quadrupole linear ion trap mass spectrometry (MS) systems. The pMRM mode offers the highest sensitivity among various acquisition modes for studying trace levels of metabolites of the herbicide clomazone in plants. Additionally, this method allows for the identification of positional isomers of metabolites.
