Hydrocarbon Type Analysis and Analytical Deviations of Pure Hydrocarbons
Mass spectrometer analyses of pure hydrocarbons and hydrocarbon mixtures have been utilized to study the relationship of total ionization to sample pressure, weight and volume. The concept of constant total ionization per unit volume is acceptable and can be utilized to compare hydrocarbon type analysis procedures. Sources of error in several published methods are described. A revised type analysis method which is based upon the correction of minor deviations from the total ionization-volume relationship is proposed.
