       Mass-spectrometer analysis of alcohols or mixtures of oxygenated compounds containing them has been difficult because of strong sorption tendencies of these materials.  In an examination of the erratic behavior of the alcohol spectra, it was found possible to minimize the effect of these difficulties by minor changes in the mass-spectrometer sample inlet system sufficient to permit analysis of synthetic mixtures of oxygenated compounds.  It is shown by alternate analyses of known mixtures widely varying in concentration of light and heavy alcohols that the different materials can be separated in the mixture spectra and that any effect of 1 sample upon a succeeding one is insignificant.  Analysis of a synthetic mixture of the 4 butanol isomers shows that alcohol isomers are also readily resolved.  That the errors in the analyses are relatively small demonstrates that sufficient accuracy can be obtained in the separation of alcohols to meet normal analytical needs.  Analysis of the 4 butanol isomers mixed with water demonstrates that the presence of water does not prevent precise results and that water can be determined accurately.  Analyses of complex mixtures show that other oxygenated compounds can be determined with adequate precision in the presence of alcohols and water.
