1. Chemical properties
- Composition:The stationary phase is composed of 5% phenyl and 95% methyl polysiloxane, which is a low-polarity stationary phase. The introduction of phenyl enhances the selectivity of the stationary phase to aromatic compounds, and the methyl part provides good non-polar properties.
- Polarity:Weak polarity, suitable for analyzing non-polar or weakly polar compounds, such as alkanes, halogenated hydrocarbons, polycyclic aromatic hydrocarbons, etc.
- Thermal stability:The maximum operating temperature is usually 350℃, with good thermal stability, suitable for high-temperature analysis.
- Chemical bonding:The chemical bonding technology is used to bond the stationary phase to the inner wall of the capillary through covalent bonds, which improves the stability and life of the stationary phase.
2. Physical properties
- Temperature range: Generally applicable to the temperature range of -60℃ to 340℃, meeting different analysis requirements.
- Column bleed rate: Ultra-low column bleed rate, ensuring the accuracy of the analysis results and the long life of the chromatographic column.
- Various specifications: Provide a variety of lengths (30m, 50m, 60m, etc.), inner diameters (0.25mm, 0.32mm, 0.53mm) and film thicknesses (0.25μm, 0.5μm, 1.00μm, etc.) to adapt to different analytical tasks.
