TECHNIQUES Stable isotope labelling processes when it comes to introduction of [2 H9 ]-TMS or 18 O were founded to generate perdeuterotrimethylsilylated, mixed deuterated and 18 O-labelled derivatives for 13 different hydroxysteroids. Fragmentation proposals were substantiated by comparison regarding the abundances of isotopic labelled and unlabelled fragment ions in device mass resolution GC/MS. Specific fragmentatioated fragment ion generation in unit mass resolution GC/
