Fast Simulated Distillation Based on Agilent 6890N Gas Chromatograph

Abstract: A rapid simulated distillation method is described for analysis of petroleum fractions boiling within the range of ASTM D2887 [1]. The method employs an Agilent 6890N gas chromatograph (GC) equipped with a split/splitless inlet, flame ionization detector (FID), oven insert, and 3-meter 180-μm id capillary column. A SIMDIS software package is partially integrated into the GC ChemStation for data analysis and SimDis calculations. Compared to conventional ASTM D2887, the accelerated method yields run times at least two times faster. It yields results comparable to traditional D2887, and agrees with the guidelines of ASTM method D2887 based on published results for the reference gas oil (RGO).
