Agilent Technologies has introduced the Large Valve Oven for its 7890B gas chromatograph system. This versatile, high-capacity external oven can be configured to support complex, multi-valve ASTM International and EN (European Standard) GC applications.
Field Forensics’ microTLC is a portable, fast and easy-to-use solution for rapid pre-screening and presumptive identification of drugs and explosive mixtures.
Gas chromatography can be successfully used in the aroma study of potable spirits, such as whisky.
Two-dimensional HPLC simplifies the determination of vitamin content in complex samples, such as a multivitamin nutritional drink, using automation and software.
Accurate and fast determination of nicotine and its metabolites provides a useful method for understanding the pharmacologic effects of nicotine and nicotine addiction.
UPC2 technology, teamed with mass spectrometry, enables simple, quick chiral analyses of fragrance compounds.
Researchers recently reported a novel approach for identifying and quantifying an important DNA repair enzyme in mammals, including humans.
Using advanced monitoring methods to assess health risk from air pollution, an environmental health scientist hopes to demonstrate for the first time in a real-world setting that air pollution can and should be regulated based on toxicology variables rather than simply on the volume of particles in the air.
The Baryon Oscillation Spectroscopic Survey Collaboration announced that it has measured the scale of the universe to an accuracy of 1 percent. This and future measures at this precision are the key to determining the nature of dark energy.
Researchers have demonstrated an unprecedented ability to peer into the dynamic, real-time reactions blazing along at scales spanning just billionths of a meter.
A new method for analyzing biological samples based on their chemical makeup is set to transform the way medical scientists examine diseased tissue.
Researchers have discovered a molecule that is produced during exercise that contributes to the beneficial effects of exercise on metabolism.
Scientists have pioneered a tabletop magnetic pulse generator that does the work of a room-sized machine– and more.
Scientists investigating heat decay from radiogenic granite in the Darling Range have discovered that the maximum heat output has exceeded previously known data.
Scientists have obtained the first detailed molecular structure of a member of the Tet family of enzymes. The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery "this gene is shut off" into other signs that say "ready for a change."
Using an ingenious setup, scientists have calculated the force of molecular motors acting on inner components of biological cells, known as organelles.
The December Chromatography Techniques cover story details a method using QuEChERS combined with GCxGC TOF/MS and a clean up method to accurately detect pesticides in tobacco samples. Other articles discuss: the value of helium, evolving column technology, and a product spotlight on a new mass spectrometer for better chromatography analyses.
Waters’ new QDa Detector gives users the power of mass detection for chromatography analyses without the cost, complexity or hassle.
As helium prices go through the roof, NIST embarks on an ambitious recycling technology.
