Zebron ZB-5HT Inferno GC Columns<br class="t-last-br" />
Zebron ZB-5HT-Inferno GC column is a non-metal GC column stable to 430 °C and provides good peak shape for acidic and basic samples

Zebron ZB-5HT Inferno GC Columns

Robust Results Up to 430 °C

  • First non-metal columns stable to 430 °C
  • Robust column for high temperature bake outs and analysis, such as biodiesel, long-chain hydrocarbons, polymers, and high molecular weight compounds
  • Provides true boiling point separation for hydrocarbon distillation methods
  • Longer lifetime with rugged high temperature, polyimide coated, fused silica tubing
  • Low activity, provides good peak shape for acidic and basic samples

Recommended Applications
Diesel Fuels, High Boiling Petroleum Products, High Molecular Weight Waxes, Long-chained Hydrocarbons, Motor Oils, Polymers/Plastics, Simulated Distillation, Surfactants, Triglycerides

Zebron Inferno Columns Win In The Lifetime Test

How does the lifetime test work?

All columns were held at 400 °C for 2 hours and then the oven was lowered to 120 °C for pentadecane analysis. The VF-5ht column broke just after 40 hours at 400 °C. The ZB-5HT had the same retention for pentadecane at 100 hours as the DB-5ht column at 40 hours — over 2X the lifetime!

Zebron ZB-5HT Inferno

Note that the VF-5ht column died around 40 hours at 400 °C whereas the Zebron ZB-5HT Inferno column maintained great retention of Pentadecane over 100 hours. Comparative separations may not be representative of all applications.
