一般說明
Application: With a phenyl content of 35%, this column offers a higher polarity option compared to columns containing a lower phenyl content. This column is useful for analyses of polar compounds because they are retained longer relative to non-polar compounds.
USP Code: This column meets USP G42 requirements.
Phase:
USP Code: This column meets USP G42 requirements.
Phase:
- Bonded
- Poly(35% diphenyl/65% dimethyl siloxane)
- 0 °C to 300 °C (isothermal or programmed)
