General description

Application: This column allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components.
USP Code: This column meets USP G16 requirements.
Phase:
  • Bonded
  • Poly(ethylene glycol)
Temp. Limits:
  • 50 °C to 280 °C (isothermal or programmed)

Application

Capillary GC column with its coated with Omegawax 250 was used for the absorption of analytes from the aqueous sample in-tube solid-phase microextraction coupled with high-performance liquid chromatography. It may also be used in blood lipid fractions by GC-MS analysis.

Other Notes

We offer a variety of chromatography accessories including analytical syringes
