General description

Application: This column has intermediate polarity due to the higher (20%) phenyl content, producing a different elution order of polar compounds for confirmational information. It is often used for analyses of aromatic analytes.
USP Code: This column meets USP G32 requirements.
• Bonded
• Poly(20% diphenyl/80% dimethyl siloxane)
Temp. Limits:
• -25 °C to 300 °C (isothermal or programmed)

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.


SPB®-20 Capillary Column may be used in gas chromatography and nitrogen-phosphorus detection, performed for the toxicological screening in order to identify and quantify barbiturates in plasma.
