Water for GCMS Analysis of Volatile Organic Compounds
Volatile organic compounds (VOCs) are carbon containing compounds that evaporate easily at normal temperatures. They are typically generated from petroleum products, plastics, paints and solvents,. Other sources are the disinfecting agents used to control microbial contaminants in drinking water. Disinfecting agents react with naturally occurring organic matter in the source water to produce VOCs known as trihalomethanes. When VOCs are spilled or improperly disposed of a portion will evaporate, but some will soak into the ground and eventually end up in drinking water supplies

December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Using LC-MS/MS to Measure Testosterone in Dried Blood Spots
December 19th 2024Testosterone measurements are typically performed using serum or plasma, but this presents several logistical challenges, especially for sample collection, storage, and transport. In a recently published article, Yehudah Gruenstein of the University of Miami explored key insights gained from dried blood spot assay validation for testosterone measurement.
