Waters Corp VanGuard Cartridge, C18, 5 μm, 3.9 mm x 5 mm

XTerra MS C18 VanGuard Cartridges extend analytical column lifespan by removing particulate mobile phase contamination. Optimized for 3.9 mm and 4.6 mm I.D. analytical columns with 5 μm sorbent, they install easily. Cartridges shield columns, improve performance by filtering impurities, and maintain UPLC, UHPLC, and HPLC separation efficiency.

  • Hybrid particle technology: silica efficiency with polymer stability for wide pH (1–12) operation.
  • Ensures excellent peak shapes for bases and high mechanical strength.
  • MS compatibility provides sharp peaks, good sensitivity, and ultra-low bleed.
  • QC tested with peptide maps for consistent performance and extended column life.
  • Sustains high pressures in UPLC system applications; allows easy scale-up.
