Simulated Distillation

What is Simulated Distillation?

Simulated distillation is used to determine the true boiling point distribution of crude oil and petroleum refining fractions by gas chromatography. It is frequently used as an alternative to time consuming and labor intensive physical distillations.


How Does Simulated Distillation Work?

There are four basic steps involved:

  • Injecting a sample into the GC
  • The analytical column separates the sample into individual components in order of their boiling points
  • Components in are detected as they elute from the column
  • Special software is used to convert the data produced by the GC into a report including: the boiling curve, initial boiling point (IBP), final boiling point (FBP)% cutoff table and other physical factors

At Separation Systems our SimDis® analyzers are based on the Agilent 7890 or 8890 GC although other GC manufacturer’s instruments can be used upon request. Our analyzers are tested  in compliance with ASTM, EN, ISO and other international standards organizations. Unlike other GC manufacturers who only guarantee their hardware and software from defects, we guarantee our GC analyzers produce the measurements you require.
