Product Description
The Waters Symmetry C18 preparative guard cartridge cartridges 10x7.8mm, 7µm, are used before Symmetry C18 HPLC columns with 7.8mm inner diameter are used. The holder 186000708 is used.
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.
