Notes:
Several reagent gases and mixed reagent gases for high pressure ion-molecule reaction ionization of samples have been investigated for use in gas chromatography-mass spectrometry analyses. The common g.c. carrier gases and their mixtures with other gases such as isobutane, ammonia, tetramethylsilane, hexafluoroacetone and nitric oxide, were studied. These reagents were used to enhance the molecular ion intensity and to simplify the spectra of steroidal alcohols and the trimethylsilyl ethers of biologically important compounds.
