General description

Application: This intermediate polarity column, designed for analyses of volatile organic compounds (VOCs), offers great retention and resolution of highly volatile compounds. Use this column in direct injection ports or coupled to purge and trap systems.
USP Code: None
Phase:
  • Bonded
  • Proprietary
Temp. Limits:
  • ≤0.32 mm I.D., <2 μm: Subambient to 250 °C (isothermal or programmed)
  • ≤0.32 mm I.D., ≥2 μm: Subambient to 230 °C (isothermal or programmed)
  • ≥0.53 mm I.D., <2 μm: Subambient to 250 °C (isothermal or programmed)
  • ≥0.53 mm I.D., ≥2 μm: Subambient to 230 °C (isothermal or programmed)

Application

VOCOL® column (diphenyl dimethyl polysiloxane with crosslinking moieties) may be used for their relevancy to the purge-and-trap technique and GC/MS analysis of 34 volatile organics. It was also found suitable in being used for determination of volatile compounds by whole column cryotrapping.

Other Notes

We offer a variety of chromatography accessories including analytical syringes
