Waters, 186007206, XSelect Peptide CSH C18 Guard Column, 130Å, 5 µm, 30 mm X 10 mm, 1K - 15K, 1/pk

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

Additional Information
XSelect Peptide CSH C18 Guard Column, 130Å, 5 µm, 30 mm X 10 mm, 1K - 15K, 1/pk An HPLC column is much more than just a product for particle separations and LC-MS analyses, it’s an important tool that you need to perform at its best across multiple assays. But how do you protect an HPLC column from harmful contaminants? With the XSelect Peptide CSH C18 Guard Column, you can do exactly that and so much more. This HPLC Guard Column seamlessly incorporates into your existing workflow to provide superior column protection. And when it’s worn out, you need only replace it with another guard column. Add the XSelect Peptide CSH C18 Guard Column to your analytical workflow today and you’ll be better protected from harmful particulate contaminants. The XSelect Peptide CSH C18 Guard Column is packed with the same packing that the XSelect Peptide CSH C18 Column has, ensuring that you have the same stationary phase to work with. What’s more, this HPLC guard column has the same inner diameter as the analytical column. This kind of precision between the guard and analytical columns helps to mitigate any potential backpressures that might sneak their way through. This HPLC guard column isn’t the only part of the column protection system, though. You still need the guard column holder to properly apply this column protection process. Simply buy the Holder Kit for Cartridge and Guard Columns to get the remaining parts you need. This HPLC column protection workflow is designed in multiple components to prevent the need of full system replacement. When parts become worn, you can order genuine replacement parts from Waters and get back to the experiments that matter. When you shop at Waters Corporation, you’re sure to find a truly massive selection of LC-MS products, resources and equipment designed specifically to help you be successful in the lab. From quality control reference materials and lab informatics to full LC-MS systems and solvent managers, we have everything you need. Shop lab equipment to explore everything we have to offer.

FAQ
What is the Function of a Guard Column in HPLC? The function of a Guard Column in HPLC is to remove particulate contaminants and other absorptive compounds from the mobile phase stream and samples, in turn prolonging overall column life.
