A simple method for gas chromatographiclmass spectrometric identification of A5*7-sterols and their acetates in complex sterol mixtures is proposed. It is based on the fact that they are more readily dehydrated (respectively deacetylated) at high temperatures, compared with A5-sterols. Sterol mixtures from four marine invertebrates were investigated by this method.

An improved, combined gas chromatographic mass spectrometric assay for the estimation of norphenazone in urine is described. A structural analogue of norphenazone is used as internal standard and derivatization of both norphenazone and the analogue gives these compounds better gas chromatographic pr
