Description

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.
Phase:

• Bonded
• Poly(20% diphenyl/80% dimethyl siloxane)

Temp. Limits:

• -25 °C to 300 °C (isothermal or programmed)

Application

SPB^®-20 fused silica capillary column is suitable for separating amino acid and keto acid by gas chromatography coupled with mass spectrometry.
