1 Scope

GB/T 18340 provisions of this part of the Mass Spectrometry group composition of gasoline, calculation and analysis of quality requirements. This section applies to the determination of condensate, or light crude oil (95% distillate temperature below 196 ℃) in three and three kinds of aromatic hydrocarbon saturation Family composition. Olefin content in the sample is less than 3%. Principle 2 Sample by the direct injection system is vaporized into the mass spectrometer by electron bombardment ion source to obtain a mixed mass chromatogram of the sample. Each Plus intensity of the peak and the corresponding inverse matrix coefficients Hydrocarbon multiplying the determined content in the sample group components.
