Mass spectrometry in sports drug testing : characterization of prohibited substances and doping control analytical assays / Mario Thevis
Edité par Wiley - 2010
"This book provides a detailed overview about the mass spectrometry of numerous classes of therapeutics and agents relevant to doping control laboratories, the necessity of various analyzers enabling the detection of low- and high molecular weight drugs as well as the discrimination between endogenously produced and synthetically derived compounds. Typical assays including sample preparation, chromatographic separation and mass spectrometric analysis are presented highlighting the comprehensiveness of drug testing in modern doping control laboratories"--Provided by publisher
