Symmetry C18 Prep Column, 300Å, 5 µm, 19 mm X 150 mm, 1/pkg

The Waters Symmetry300 C18 HPLC column 150x19mm, 5µm, is based on an octadecylsilyl phase (other designations: ODS, RP-18, C18) on wide-pore 300 Å silica and is suitable for use in reversed-phase mode. The large pore size improves access of larger peptides and proteins to the stationary phase and increases recovery and peak shape. The application range of Waters Symmetry300 C18 includes peptides, protein fragments, biopharmaceutical RP analysis and methods involving larger biomolecules.

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.
