General Description

Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.Application: This non-polar general purpose column provides primarily a boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.
USP Code: This column meets USP G27 and G36 requirements.
Phase:

• Bonded
• Poly(5% diphenyl/95% dimethyl siloxane)

Temp. Limits:

• ≤0.32 mm I.D., <2 μm: -60 °C to 320 °C (isothermal or programmed)
• ≤0.32 mm I.D., ≥2 μm: -60 °C to 300 °C (isothermal or programmed)
• ≥0.53 mm I.D., <2 μm: -60 °C to 300 °C (isothermal) or 320 °C (programmed)
• ≥0.53 mm I.D., ≥2 μm: -60 °C to 260 °C (isothermal) or 280 °C (programmed)

Application

It may be used as stationary phase for determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography.
