1. Chemical properties
Composition: It is composed of 6% cyanopropylphenyl and 94% dimethylpolysiloxane. The cyanopropylphenyl part is bonded to the dimethylpolysiloxane chain, giving it a unique separation ability.
Stability:
- Thermal stability: It can be used in a wide temperature range of -20℃ to 260℃ (or 280℃), which can meet different analytical needs.
- Chemical stability: It is inert to active compounds, reduces adsorption and decomposition, and improves analytical accuracy.
Interfacial activity: It forms reversible adsorption between different phases, which is suitable for analyzing a variety of compounds, including volatile organic compounds, residual solvents, pesticides, etc.
2. Physical properties
Temperature application range: Usually -20℃ to 260℃ (or 280℃), which can meet different analytical needs.
- Column bleed rate: Ultra-low column bleed, improving analytical accuracy and column life.
- Diverse specifications: Provide a variety of lengths (15m, 30m, 60m, etc.), inner diameters (0.25mm, 0.32mm, 0.53mm) and film thicknesses (0.25μm, 1.00μm, etc.) to meet different analysis needs.
