Waters, 186005491, XSelect CSH C18 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk

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.

Additional Information
XSelect CSH C18 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk When you’re performing preparative HPLC assays for method development, it’s important that your column is free of any contaminants that could potentially cause data variability. That’s why we’re happy to provide the XSelect CSH C18 Prep Guard Cartridge. This guard cartridge contains the same column packing material exhibited in the XSelect CSH C18 Column, making it a stable solution for enhanced column protection. What’s more, when this C18 guard cartridge becomes worn and needs to be replaced, you can just switch it out with another genuine guard cartridge replacement from Waters. Add the XSelect CSH C18 Prep Guard Cartridge to your lab’s procurement list today, or add one to your cart for shipping! The science behind the guard cartridge is simple – the guard cartridge is installed between the mobile phase injector and the analytical column to act as a barrier against contaminants in the mobile phase stream. But to properly install the guard cartridge, you need the Prep Guard Holder as well. Without the prep guard holder, you cannot incorporate the XSelect CSH C18 Prep Guard Cartridge into your analytical workflow. XSelect Columns are amongst the most popular HPLC columns on the market. But thanks to that popularity, that also means scientists across the globe are using these columns repeatedly across multiple assays. If proper column regeneration and cleaning procedures are not followed, an XSelect Column may not perform as well as it should. Thanks to the XSelect CSH C18 Prep Guard Cartridge, concerns over contamination can be greatly reduced. It’s the guard cartridge’s top priority to protect your analytical column from harmful contaminants, and it achieves that by offering the same base chemistry as the analytical column. After properly installing your new XSelect CSH C18 Prep Guard Cartridge, take a look around your lab. If you find that your lab requires more chromatography consumables or LC-MS products to be successful, make sure to shop lab equipment at Waters to see everything we have to offer. We pride ourselves on offering everything a scientist needs to be successful in an LC-MS lab.
