HPLC Guard Columns and Cartridges
Waters Corp Viridis BEH VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
Designed and tested for the ACQUITY UPC2 system, the Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
Waters Corp XTerra MS C8 VanGuard Cartridge, 125à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
XTerra MS C8 VanGuard Cartridge, 125à , 2.5 µm, 2.1 mm X 5 mm, 3/pk
Waters Corp Symmetry C4 Sentry Guard Cartridge, 300Å, 5 µm, 3.9 mm X 20 mm, 2/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
Waters Corp XTerra MS C8 Prep Guard Cartridge, 125Å, 5 µm, 19 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.
