       In an attempt to analyze some oxygenated compounds by means of the mass spectrometer, using the same procedures as in the analysis of gaseous and liquid hydrocarbons, several difficulties were encountered.  Extremely long evacuation times were necessary to remove some compounds from the tube, and, even more serious, large variations in peak heights occurring in successive scanning of the sample indicated that the instrument was unable to maintain calibration.  Some of these difficulties were partly overcome by using a heated tube and a new trap design.  Results obtained with mixtures of MeOH, formic acid, methyl formate, and methylal are included.  In general, the results do not attain the precision and reproductibility of hydrocarbon analyses.
