Fast GC Capillary Columns Theory



Only good for isothermal analysis, but use as a guide.

There are Two Options

  • Reduce the number of plates – lose resolution, faster analysis times
  • Keep the number of plates constant – maintain resolution, longer run times
  • If Beta and Total Plates are the same – Chromatography can be identical

Conditions to Reduce Analysis Time by a factor of 2 to 3

  • HP 5890 GC
  • FAST SGE Capillary Column
  • Manual Pressure Regulator (30psi max)
  • He Carrier Gas
  • 20Hz FID Data Acquisition
  • 30° C/ min max Oven Program Rate
