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.

The Quality Control Reference Material portfolio is a unique collection of standards and mixtures. These products allow the user to evaluate and benchmark their chromatography system before the analysis of critical material. The products in the portfolio are all specially formulated based on the expertise of Waters scientists. The AutoPurification Dye Standard contains 3 compounds, including Thionin, Thioflavin, and Crystal Violet. This standard mix is used to confirm the benchmark performance of a Preparative/Purification System through fraction collection. This particular QCRM is specially formulated to allow the user to verify correct fraction collection. This test is highly valuable to perform upon first use/installation and any time the system has not been used or has had any changes.
