Simulated Distillation

Simulated distillation is a GC method used to characterize petroleum fractions and products, since it permits quick determination of their boiling range distribution. Samples are analyzed on a non polar chromatographic column that separates the hydrocarbons in the order of their boiling points. Hydrocarbons are correlated with the retention times, through a calibration curve obtained by running the test under the same conditions of the mixture of hydrocarbons, usually n-alkanes, covering the boiling range expected in the sample. Results are reported as a correlation between the boiling points and the percentages of the sample eluted from the column.


  • Characterization of light petroleum components or fractions (boiling point < 350 oC)
  • Characterization of heavy petroleum components or fractions (boiling point < 750 oC)
  • Replaces difficult and costly conventional distillation methods.
  • Evaluation of new crude oils.
  • Confirm crude quality.
  • Monitor crude quality during transportation
  • Provide information for the optimization of refinery processes.
