Waters, 186005418, XSelect CSH C18 Prep Guard Cartridge, 130Å, 5 µm, 19 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, 19 mm X 10 mm, 1/pk The Waters XSelect CSH C18 equipment collection includes Analytical Columns, Prep Columns and Guard Cartridges. These are typically used as general-purpose columns to provide alternative unique selectivity in contrast with other C18 sorbents. The XSelect CSH C18 Prep Guard Cartridge is designed on the Charged Surface Hybrid (CSH) technology, which assists the column in overcoming challenges that regular columns generally face, namely, peak shape asymmetry and poor landing for basic compounds, column bleed, and slow mobile-phase re-equilibrium. The XSelect CSH C18 collection of Columns, Prep Columns, and Guard Cartridges are designed to offer diverse analyte selectivity to separate closely eluting sample constituents. They will deliver unmatched selectivity and reproducibility for your chromatographic analysis. The XSelect CSH C18 Prep Guard Cartridge is made from the same packing material as the XSelect CSH C18 analytical Column, making it compatible with the analytical column and helps in protecting the column and extending its lifetime. The application of the CSH technology-based Column will provide you with many advantages, including superior peak shape for basic compounds and high peak capacity for complex mixtures; increased mass load for preparative separation without having to use ion-pairing reagents; and rapid column equilibration. CSH technology enables you to quickly change mobile-phase conditions and pH to quickly screen multiple mobile-phase conditions. With its protective and time-saving features, the XSelect CSH C18 Prep Guard Cartridge will enable you to reduce purification and lab costs, making it a vital piece of equipment to have.

FAQ
What Are The Recommended Pressure And Temperature You Can Use With The XSelect CSH C18 Prep Guard Cartridge? The XSelect CSH C18 Column is designed to withstand a pressure of 6000 psi (or 415 Bar) along with a particle size of 10 µm and pore size of 130 Å. However, it is always recommended not to cross the maximum range to ensure the best possible column lifetime and effectiveness. The recommended temperature for your equipment is 80 C under Low pH conditions and 45 C in high pH conditions.
