Sapphirus silica is based on a new 100 A ultra-high purity (99.999%) extra-treated porous spherical silica with a narrow particle size distribution and an extremely low metal content (< 10 ppm) to minimize silanol acidity and reduce surface metal sites available for chelation.
Sapphirus silica is manufactured in a GMP environment under the most rigorously controlled conditions, ensuring lot-to-lot reproducibility, consistent particle size, pore volume and chemical purity. Combined with our proprietary bonding technology this results in columns with optimal efficiency, asymmetry, and minimal back pressure. Sapphirus is available in several bonded phases covering a wide range of reversed-phase applications.
- Ultra high purity silica with completely spherical, totally porous particle.
- Well controlled narrow particle size distribution
- High bonding density.
- Minimal silanol activity due to new properitary end capping technology.
Superior Loadbility and Surface Area Accessibility
- Optimized paricle surface area, pore volume, pore volume, pore diameter and its distribution to give good surface morphology
