General description

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)
