What is a FAST GC column?

A FAST GC column has a much smaller internal diameter than a standard GC column. It is also much shorter and more flexible.

Standard column:
30m x 0.25mm ID, 0.25um film thickness

Fast column:
10m x 0.1mm ID, 0.1um film thickness

Definitions

  • Fast GC – run times in 5- 10 minutes
  • Very Fast GC – run times in a few minutes
  • Ultra Fast GC – run times less than one minute (usually several seconds)

Faster analysis can be achieved in any of the following ways

  • A fully optimized separation
  • A non-optimized separation
  • All peaks are equally important
  • Only a small number of peaks are important
