Beschreibung
Prominent experts explain the pharmacology and metabolism of benzodiazepines (LDB) and g-hydroxybutyric acid (GHB) and offer powerful and effective methodologies that will enable better detection of these drugs in various body fluids, as well as in hair. The techniques include highly sensitive immunoassay detection of LDBs, the detection of Rohypnol and other LDBs by mass spectrometry, and the ultrasensitive detection of GHB. State-of-the-art and highly practical, Benzodiazepines and GHB: Detection and Pharmacology offers toxicologists, forensic scientists, and clinical chemists today's most effective methods for detecting these widely abused drugs that are sometimes found associated with criminal acts.
