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

SPB^®-5 Capillary GC Column was used for speciation of the nitrogen compounds (quantitatively), which are polar and somewhat basic in nature, with chemiluminescence detection. It may also be used as stationary phase for determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography.Furthermore, it may also find application in being used as stationary phase in capillary column gas chromatography for determination of sterols.
