Waters, 186006958, XSelect Peptide CSH C18 Sentry Guard Cartridge, 130Å, 3.5 µm, 4.6 mm X 20 mm, 1K - 15K, 2/pk

Waters XSelect CSH130 C18 3.5 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. Please note: this guard column requires 4.6 x 20 mm Universal Sentry Guard Holder, (P/N WAT046910)

Additional Information
XSelect Peptide CSH C18 Sentry Guard Cartridge, 130Å, 3.5 µm, 4.6 mm X 20 mm, 1K - 15K, 2/pk Longer column lifetimes can lead to a more efficient and in turn, more profitable, lab for all. But to ensure increased lifetime of your analytical column, you need a sentry guard cartridge to be equipped. That’s where the XSelect Peptide CSH C18 Sentry Guard Cartridge comes in. Designed specifically for the XSelect Peptide CSH C18 HPLC Column, this cartridge seamlessly incorporates into your analytical workflow to prevent harmful chemical or particulate fouling from causing data variability. Add this column protection solution to your lab’s toolkit now, or tell your lab manager that you want the XSelect Peptide CSH C18 Sentry Guard Cartridge. What’s the main purpose of the XSelect Peptide CSH C18 Sentry Guard Cartridge? To remove chemical and particulate contaminants from the mobile phase stream. Even with the strictest sample preparation guidelines applied to your experiments, there’s still a chance the mobile phase stream carries a small amount of contaminants. Not only can this cause harmful data variation, it may require you to repeat your assays to validate data. Much of that concern can be removed easily when you purchase and apply the XSelect Peptide CSH C18 Sentry Guard Cartridge. The XSelect Peptide CSH C18 Sentry Guard Cartridge is packed with the exact same packing material used in the XSelect Peptide CSH C18 Column. This helps to promote a streamlined analytical workflow whenever you’re in the lab. Just simply apply the sentry guard cartridge between the injector and analytical column, then you’re ready to get back to the important analyses that matter. What’s more, this cartridge can protect your analytical HPLC column from worn pump and rotor seals from the injector. After you purchase the XSelect Peptide CSH C18 Sentry Guard Cartridge, it’s important that you also have a properly functioning guard column or cartridge holder as well. Add the Holder Kit for Cartridge and Guard Columns to your lab’s procurement list and you’ll be ready to incorporate the guard cartridge properly into your workflow. Shopping at Waters is one of the best things a scientist can do for their lab. We truly have everything you need to run successful LC-MS analyses, verify that data and draw conclusions.
