The role of gas chromatography mass spectrometry - Instrumental techniquesin forensic urine drug testing

This article discusses the application of GC/MS instrument techniques to ur ine drug testing. Remember that GC/MS is a technique combining gas liquid c hromatography (GLC) separation with mass spectrometric detection. This mean s that good GC/MS results are highly dependent on good chromatographic para meters. Although it may seem self-evident, many users encounter GC.MS probl ems that could be readily avoided by optimizing chromatographic parameters. In fact, most GC/MS problems in the clinical or forensic toxicology labora tory are probably chromatographic in nature.
