New Test To Detect Triclosan in Water
A team of scientists from Agricultural Research Service (ARS) and Abraxis, Inc. compared the a new triclosan test, called "magnetic particle enzyme immunoassay," to the more traditional method-gas chromatography-mass spectrometry (GC-MS). They hope that this test, which detects triclosan at a concentration of 20 parts per trillion (ppt)-the equivalent of 1 ounce in 31 million tons, can expedite environmental monitoring of this widely used antibacterial agent in rivers, wells, and other bodies of water.

"This new technique is capable of measuring the triclosan content of a large number of water samples much faster than previous methods," says ARS chemist Weilin L. Shelver. "We plan on expanding the assay's use into the detection of triclosan in other environmental matrices and food."
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
Altering Capillary Gas Chromatography Systems Using Silicon Pneumatic Microvalves
May 5th 2025Many multi-column gas chromatography systems use two-position multi-port switching valves, which can suffer from delays in valve switching. Shimadzu researchers aimed to create a new sampling and switching module for these systems.
New Study Reviews Chromatography Methods for Flavonoid Analysis
April 21st 2025Flavonoids are widely used metabolites that carry out various functions in different industries, such as food and cosmetics. Detecting, separating, and quantifying them in fruit species can be a complicated process.
