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).

Analysis of Environmental Contaminants in Water Using an Agilent 6470 LC/TQ Instrument

The analytical demands for detecting organic contaminants in water at low ng/L level have pushed the development of new methodologies using LC/TQ instrumentation. In this regard, and in the last few years, advances in sensitivity and selectivity have made this challenge possible. This webinar will focus on the use of the new 6470 LC-MS-MS from Agilent Technologies for the sub ng/L level detection of several pharmaceuticals and pesticides in surface waters. Examples of optimization of several source...

Last Month's Most Accessed Feature: Atmospheric pressure MS method gives hope on OPEs

Although they have previously tended to keep a low profile, organophosphate esters are widespread chemicals, which have become a hot topic in the analytical world due to their potential harmful effects on health and the environment. Researchers from France and the Lebanon have used mass spectrometry with an APCI source to identify some of these compounds, comparing the results with standard EI spectra.

GC×GC and an electronic nose-based ultra-fast GC with chemometric analysis have both been used to distinguish between the vodkas produced from different raw materials.

Male infertility is often caused by poor sperm motility (i.e. poor ‘swimming’), also known as asthenozoospermia, but the causes of this condition are not well understood. Researchers from Nanjing Tech University compared the concentrations of a range of seminal fatty acids and other metabolites from those with asthenozoospermia and healthy controls using GC-MS, the results showing some significant differences between the two groups.

The leaves of the qat (or khat) tree are widely chewed as a stimulant in Yemen and the Horn of Africa; they contain the stimulant alkaloids cathinone, cathine and (1R,2S)-norephedrine. Researchers from Colorado State University examined leaves from 43 related plant species by GC/MS, using a double derivatisation method, in order to determine if any of these contained the same stimulant alkaloids.
