HPLC chromatography column VanGuard™

for pharmaceutical applications

Even under the best conditions, analytical LC columns deteriorate over time from chemical or particulate contamination. With VanGuard Column Protection products, you can now achieve maximum lifetime and performance from your columns. VanGuard column products are optimized to protect and prolong analytical column lifetimes without compromising chromatographic performance. Available in a wide selection of particle sizes and stationary phases across HPLC, UHPLC, and UPLC, VanGuard Column Protection products are ideally suited for the physical and chemical protection of all Waters analytical columns. Overview Remove particulates and chemical contamination found in samples and mobile phases Maintain separation resolution and efficiency by minimizing chromatographic peak dispersion and tailing with patent pending low dead volume design Eliminate leaks and voids by connecting directly to Waters UPLC, HPLC, and UHPLC columns Compatible with pressures up to 18,000 psi for UPLC and UHPLC columns Recommended Use: To extend LC column lifetime while maintaining chromatographic performance.
