Product Description
Performance Characteristics and Benefits
- High-purity, tightly specified silica
- Low residual silanol activity
- Reproducible peak shapes
- Shield phases with embedded polar groups
- 100 and 300 Å platforms
Additional Notes
Symmetry is based on high-purity silica and strictly controlled manufacturing and packing specifications. The classic C18 and C8 phases are designed to minimize unwanted silanol interactions and ensure reproducible peak shapes. In SymmetryShield, a polar group is embedded in the alkyl phase, which alters the selectivity and behavior of basic analytes compared to conventional alkyl phases. Symmetry300 uses a wide-pore 300 Å silica and extends the series to peptides, proteins, and other larger biomolecules.
