C18 Guard Columns

C18 Guard Columns
Prep Guard Cartridge 10 mm x 10 mm
SKU: 186005491
Category: Columns
XSelect CSH C18 columns can be used as general purpose columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps you overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.

Waters XSelect CSH130 C18 5 µm particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for peptides using either FA- or TFA-containing mobile phases. The fact that the performance of a CSH130 C18 column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications

ACQUITY UPLC HSS C18 SB columns are used for low pH separations that contain complex mixtures of basic and non-basic compounds. ACQUITY HSS C18 SB columns give you alternative analyte selectivity compared to most modern, high coverage, fully endcapped C18 stationary phases. ACQUITY HSS C18 SB columns are fully scalable and transferable to HPLC separations. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.

SKU: 186001001
Category: Columns
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.

Waters CSH130 C18 based particles contain a low and carefully-defined concentration of positive charges that yield comparatively excellent peak shape for peptides using either FA- or TFA-containing mobile phases. The fact that the performance of a CSH130 C18 column exhibits little dependence on strong ion pairing agents makes it ideal for LC or LC-MS applications. Packed in ultra-low dispersion hardware, XSelect CSH130 C18 2.5 µm eXtended Performance [XP] columns enable exceptional separation performance, robustness and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption. The VanGuard pre-column connects directly to the inlet of an eXtended Performance column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
