Abstract
Microbore columns packed with 7-µm polysiloxane bonded silica are utilized for simulated distillation (SIMDIS) of petroleum materials by supercritical fluid chromatography (SFC). Preliminary data show that efficient, short microbore (1-mm i.d.) columns allow fast analysis and calibration up to C100 with good reproducibility and quantitation. No flow splitting is required for sample injection and flame-ionization detection. The relative high loadability of packed columns also permits neat injection (without dilution) of relatively nonviscous crude oils. The packed column SFC-SIMDIS data are in good agreement with previous data obtained by capillary SFC and vacuum thermogravimetric analysis (VTGA).Keywords
