Using the combined electrostatic analyser-magnet scan facility of a double focusing mass spectrometer, the daughter ion peak for the fragmentation, M-57+ leads to M-57-76+, of a 5alpha-dihydrotestosterone tert-butyl-dimethylsilyl ether was monitored during gas chromatography mass spectrometry. The detection limit was approximately 20 pg. The steroid was detected by this method in an extract of human blood plasma.
Gaskell et al. (1978) studied this question.
