Screening procedure for detecting butyrophenone and bisfluorophenyl neuroleptics in urine using a computerized gas chromatographic-mass spectrometric technique.
A method for the identification of butyrophenone and bisfluorophenyl neuroleptics and their predominant basic metabolites in urine after acid hydrolysis is described. The acetylated extract is analysed by computerized gas chromatography-mass spectrometry. An on-line computer allows rapid detection using mass fragmentography with the masses m/e 112, 123, 134, 148, 169, 257, 321 and 189, 191, 223, 233, 235, 245, 287, 297. The identity of positive signals in the reconstructed mass fragmentograms is established by a comparison of the entire mass spectra with those of standards. The mass fragmentograms and the underlying mass spectra are documented.
