โœฆ Synopsis

An established gas-liquid chromatographic method for analysis of trimethylamine in urine was substantially improved by the use of an exchangeable lithium hydroxide, kieselguhr precolumn. Biological samples were acidified immediately upon collection and were analyzed by direct injection onto the precolumn. Using this technique, a normal urinary level of trimethylamine was found to be 5.0 + 3.1 ymol/mmol creatinine in a group of 17 adults.

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
