Waters Corp Waters C18 Prep Guard Cartridge, 5 μm, 10 mm X 10 mm
This guard cartridge is ideal for HPLC method development, offering a universal column for most HPLC separations across a mobile phase pH range of 1–12. It minimizes system volume addition, maintaining preparative column efficiency and resolution while protecting against contaminants. This cartridge purifies samples by trapping impurities, preventing negative impacts on separation and purity.
- Trifunctionally bonded C18 ligand provides wide usable pH range, superior low pH stability, and ultra-low column bleed.
- 5 μm particle size balances protection and pressure drop, ensuring effective filtration.
- Regenerable with appropriate solvent washes to extend usable life.
- Designed for HPLC preparative systems.
- Low silanol activity and spherical particle shape.
- Supports LC/MS and LC techniques.
