Description

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)

Application

• Gas chromatography-mass spectrometry determination of conjugated linoleic acids and cholesterol oxides and their stability in a model system.: This study demonstrates the use of the Equity-5 Capillary GC Column in the analysis of fatty acid esters and cholesterol oxidation products, providing insights into their thermal stability and decomposition pathways (Yen et al., 2010).
