Removes Particulates and Chemical Contamination

The often complex sample matrices encountered in pharmaceutical, natural product, environmental, and industrial chemical analysis prematurely shorten analytical column lifetime and degrade chromatographic performance. Waters VanGuard Column Protection products help improve analytical column performance by removing particulate and chemical contamination that may be present in the mobile-phase stream.

Column Protection Benefits

Pre-columns Maintain UPLC Column Efficiency

The one-piece, patented design of the VanGuard Pre-columns does not compromise the holistic approach to higher efficiency, greater resolution, and increased throughput of ACQUITY UPLC separations. The low dispersion 2.1 x 5 mm these 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

These Cartridge Columns are a universal solution to extend all HPLC and UHPLC column lifetime. 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.
