产品介绍
产品特点:
Equity-5 色谱柱 :
Application: This popular column is designed for general purpose applications where a non-polar column is required. The low phenyl content provides thermal stability compared to 100% poly(dimethyl siloxane) columns.
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 325 °C (isothermal) or 350 °C (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)
