GAS OIL ANALYZING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an analytical method for clearing up a detailed composition on normal paraffin and isoparaffin in gas oil. SOLUTION: This gas oil analyzing method by a GC/FIMS analytical method analyzes the gas oil by reading ionic strength of a first mass spectrum of integrating the whole mass spectra and a second mass spectrum integrated with every carbon number of normal paraffin or a third mass spectrum of collectively integrating mass spectra of the whole normal paraffins; or analyzes the gas oil by determining the peak area of the peak by discriminating the peak of isoparaffin and normal paraffin from a mass chromatogram.
