产品说明
一般描述
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)
- -25 ℃ to 300 ℃ (isothermal or programmed)
应用
SPB®-20 fused silica capillary column is suitable for separating amino acid and keto acid by gas chromatography coupled with mass spectrometry.
其他说明
We offer a variety of chromatography accessories including analytical syringes
