XSelect CSH C18 XP Column, 130Å, 2.5 µm, 4.6 mm X 75 mm, 1/pk
XSelect CSH C18 columns are general-purpose C18 columns that provide alternative selectivity compared to other C18 sorbents. The Waters XSelect CSH C18 XP Column delivers unmatched selectivity and reproducibility for your chromatographic analysis. The XSelect CSH C18 XP Column has been designed to offer diverse analyte selectivity to separate closely eluting sample constituents and provides alternative selectivity compared to other C18 sorbents available for commercial use.
The Charged Surface Hybrid (CSH) technology embedded within the column enables your system to overcome typically observed column-related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration. By utilizing the XSelect CSH C18 XP Column, you will be able to achieve higher resolution separations that are needed for complex samples in order to isolate and quantify them. The lab equipment makes this possible through the unique phases of the analytical column, which combine efficiency and selectivity to enhance the resolution of very complex samples.
The XSelect CSH C18 eXtended Performance [XP] column is packed in ultra-low dispersion hardware, and it enables you to attain exceptional separation performance, robustness, and throughput for HPLC assays while enabling a seamless transition path toward UPLC adoption. The XSelect CSH C18 XP Column offers improved loading capacity and particle size scalability similar to other fully-porous particle columns. This lab equipment offers maximum method development freedom, especially when using low pH mobile phases as the non-end-capped sorbent of the XSelect CSH C18 XP Column offer enhanced retention of acidic compounds.

We also recommend that you review the XSelect CSH C18 XP VanGuard Cartridge, 130Å, 2.5 µm, 2.1 mm X 5 mm, 3/pk; this VanGuard Cartridge is designed to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream. This cartridge is optimized to protect all 2.1 mm and 3.0 mm I.D. XSelect CSH C18 analytical columns containing 2.5 µm sorbent particles.
What Pressure Can Be Used With The XSelect CSH C18 XP Column?
The XSelect CSH C18 XP Column is designed to withstand a pressure of 18000 psi (or 1240 Bar) along with a particle size of 2.5 µm and pore size of 130 Å. However, it is always recommended to not cross the maximum range to ensure best possible column lifetime and effectiveness.
