VanGuard Column Protection

VanGuard Column Protection

Protect and prolong analytical column lifetime

Protect and prolong analytical column lifetime

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.

Specifications

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.

Remove particulate and chemical contamination

Complex sample matrices encountered in pharmaceutical, natural product, environmental, and industrial chemical analysis prematurely shorten analytical column lifetime and degrade chromatographic performance. VanGuard Column Protection products help improve analytical column performance by removing particulate and chemical contamination that may be present in the mobile-phase stream. The low dead volume design minimizes chromatographic peak dispersion and tailing to maintain separation resolution and efficiency.


Pre-columns maintain UPLC column efficiency

With the low dispersion, one-piece patented design of the VanGuard Pre-column, you can achieve a holistic approach of higher efficiency, greater resolution, and increased throughput with ACQUITY UPLC separations. The pre-column connects directly to the inlet of the ACQUITY UPLC Column and is available in all ACQUITY UPLC Column stationary phases.


Cost-effective protection for HPLC and UHPLC columns

VanGuard cartridges and pre-columns are a universal solution to extend all HPLC, UHPLC, and UPLC column lifetimes. Simply replace the cartridge instead of your more expensive analytical column to regenerate the original separation performance. The reusable holder is designed with an adjustable ferrule so that it can be attached to any column inlet. The cartridges provide column protection over a wide variety of separation conditions, while the low volume design maintains resolution and separation efficiency during routine use.


A breakthrough in guard column performance

VanGuard FIT (Fully Integrated Technology) represents a more purposeful approach to guard column design and functionality, providing unprecedented ease of use coupled with an ultra-low dispersion format. The innovative all-in-one guard/column design translates to optimal performance for even the most critical separations.
