Mass Spectrometry Test for Sports Doping
July 15th 2008Researchers at the University of Utah's (Salt Lake City) Sports Medicine Research and Testing Laboratory developed a test for testosterone and epitestosterone in urine that uses liquid chromatography with tandem mass spectrometry detection (LC-MS-MS).
Branching in High Molar Mass Synthetic Amyloses
July 10th 2008Wyatt Technology has published an application note on branching in high molar mass synthetic amyloses. Amylose is an occasionally-branched biopolymer and, together with amylopectin, the hyper-branched component, a constituent of starch. Determination of branching in amylopectin on the basis of amyloses may be performed with the help of synthetic amyloses. Synthetic amyloses from enzymatic (phosphorolytic) reaction were checked for their linearity.
Planar Chromatography — Back to the Future?
July 1st 2008Planar chromatography celebrates its 70th birthday. The technique dates back to 1938 when, at the Pharmaceutical Institute in Kharkov, Ukraine, N.A. Izmailov and M.S. Shraiber first devized a circular thin-layer chromatogram,1 which was called spread layer or spot chromatography at the time.

LC-MS-MS Analysis of Antibiotics in Wastewater
July 1st 2008This article describes the development of a method for the determination of sulphonamide antibiotics at trace levels in effluent wastewaters by LC?MS?MS to determine its capability for the detection of pharmaceutical compounds before they reach the aquatic environment.
