Urinary 19‐norandrosterone purification by immunoaffinity chromatography: application to gas chromatography/combustion/isotope ratio mass spectrometric analysis

Abstract

Abstract The detection of exogenous 19‐norandrosterone (19‐NA) in urines was investigated by using gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS). 19‐NA is, for the first time to our knowledge, isolated from urinary matrix by specific immunoaffinity chomatography (IAC) before analysis. The sample preparation consisted of a preliminary purification of urine by solid‐phase extraction after hydrolysis by β‐glucuronidase. Unconjugated 19‐NA was thus isolated by IAC and directly analysed by GC/C/IRMS. Optimisation of IAC purification was achieved and the reliability of the technique for anti‐doping control is discussed. Copyright © 2002 John Wiley & Sons, Ltd.
