DETECTION OF TRACE QUANTITIES OF ALIPHATIC-ALCOHOLS USING DERIVATIZATION TECHNIQUES SUITABLE FOR POSITIVE AND OR NEGATIVE-ION GAS-CHROMATOGRAPHY CHEMICAL IONIZATION MASS-SPECTROMETRY

Improvements in the analytical methodology used in the gas chromatographic/chemical ionization mass spectral analysis of alphatic alcohols are described. Improved chromatographic resolution using polysiloxane-deactivated fused silica capillary columns is shown. The trimethylsilyl, as well as the trifluoroacetyl, pentafluoropropionyl, and heptafluorobutyryl O-acyl derivatives are prepared, and the reaction conditions discussed. The chromatographic separation of positional isomers of dodecen-1-ol for each derivative investigated is shown, as well as a description of the elution time shift caused by the conversions of a specific positional isomer to each of the derivatives.
