22 May 2012

This note describes the analysis of some common drugs of abuse by Gas Chromatography—Time-of-Flight Mass Spectrometry (GC-TOFMS). In addition to using standards, two real-life samples of blood and urine extracts were analyzed to demonstrate the power of the technique in handling samples containing small amounts of drugs in demanding matrices.
