Compound-specific stable carbon isotope analysis by gas chromatography/combustion/isotope ratio mass spectrometry is an important method for the detection of steroid abuse in athletes. However, steroids in their natural form exhibit poor chromatographic resolution, while derivatization adds carbon thereby corrupting the starting stable isotopic composition. Hydropyrolysis is a new approach, which defunctionalizes steroids but leaves their carbon skeleton intact. The process improves chromatography, allowing the faithful measurement of carbon isotope ratios and enabling a more effective apportionment for the source of steroids and their metabolites.
