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).
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...Read More
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.Read More

Frozen meat products can be thawed out and passed off as fresh, chilled meats, thus fetching a higher price. Researchers at Warsaw University of Life Sciences and University College Dublin have developed a method to differentiate between chilled and frozen pork using an electronic nose device containing an ultra-fast gas chromatography unit.

2-Methylimidazole and 4-methylimidazole, compounds found in cola drinks and dark beers, are suspected to be possible carcinogens on the basis of animal studies. Scientists from Woosuk University in South Korea have developed an improved method for methylimidazole analysis using derivatisation followed by GC-MS/MS.View All Ezines

Continuous improvements in GC/MS and LC/MS have revealed a stunning array of pharmaceuticals and personal care products (PPCPs) in municipal wastewaters. What is known from global studies is that exposure to biologically active compounds, even at ng/L concentrations, can impact endocrine systems in nature and manifest as negative impacts like altered gene regulation, the presence of mixed reproductive tissues (intersex) and skewed sex ratios. Advancing Canadian Wastewater Assets (ACWA) is a research...
