Waters, 186005257, XSelect CSH C18 Column, 130Å, 3.5 µm, 2.1 mm X 150 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 Column, 130Å, 3.5 µm, 2.1 mm X 150 mm, 1/pk Use the XSelect CSH C18 Column to deliver unmatched selectivity and reproducibility for your chromatographic analysis. The lab equipment is designed to offer diverse analyte selectivity to separate closely eluting sample constituents. The column can be used as a general-purpose column that provides alternative selectivity compared to other C18 sorbents available for commercial use. The Charged Surface Hybrid (CSH) technology embedded in the column will help you overcome column-related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration. With the XSelect CSH C18 Column, you can conduct higher resolution separations that are required for complex samples in order to isolate and quantify the samples. The XSelect CSH C18 Column makes this possible by the unique phases of the analytical column which combine efficiency and selectivity to enhance the resolution of very complex samples. When you are developing a chromatographic assay the lab equipment will save time and effort while being fully compatible with all HPLC, UPLC, and UHPLC technologies. In addition to this, the analytical column makes it possible for you to develop robust methods quickly as it offers excellent batch-to-batch reproducibility. Outstanding performance and equivalent backpressure are also important benefits you get with the XSelect CSH C18 Column when compared to core-shell columns. Additionally, like other fully-porous particle columns, the XSelect CSH C18 Column also offers improved loading capacity and particle size scalability due to the use of the Charged Surface Hybrid (CSH) technology in the analytical column. CSH Technology, which is the next evolution of particle technology, improves all facets of liquid chromatography performance in acidic, low ionic strength mobile phases significantly. The column also offers maximum method development freedom, especially when using low pH mobile phases. This is because the non-end-capped sorbent of the XSelect CSH C18 Column offers enhanced retention of acidic compounds. It also comes packed in ultra-low dispersion hardware, enabling outstanding separation performance, and a seamless transition path toward UPLC adoption, making the XSelect CSH C18 Column an integral piece of lab equipment.

FAQ
What Is Meant By Basic Compounds? If a compound that contains an OH group also contains a metal ion, then it is a base. The addition of water, which enables the formation of "free" OH groups, i.e. hydroxide ions, results in a solution that is basic.
