XSelect CSH C18 Column, 130Å, 5 µm, 3 mm X 150 mm, 1/pk
The XSelect CSH C18 column provides higher selectivity than typical C18 sorbents and can be utilized as a general-purpose column. The Charged Surface Hybrid (CSH) technology used in the construction of these columns helps to resolve common column-related concerns such as peak shape asymmetry and poor landing for basic chemicals, column bleed, and sluggish mobile-phase re-equilibrium.
With the XSelect CSH C18 Column, you may perform high-resolution separations, which are essential for complex samples in order to identify and quantify components. To improve the resolution of exceedingly complex samples, the different phases of the XSelect CSH C18 Column combine selectivity and efficiency. By using this laboratory equipment, you can design a chromatographic test more quickly and easily while attaining amazing separation resilience, performance, and throughput for HPLC investigations.
Because of its excellent batch-to-batch repeatability, greater loading capacity, and better particle size scalability, the XSelect CSH C18 analytical column makes it simple to develop dependable procedures. As a result, the XSelect CSH C18 Column must be present in your laboratory. CSH Technology provides enhanced peak shape for simple drugs and increased peak capacity for complex mixtures. With the use of CSH, you will be able to increase the mass load for preparative separation without utilizing ion-pairing reagents. Because it promotes rapid column equilibration, it allows for rapid changes in mobile-phase conditions and pH to quickly screen a variety of mobile-phase conditions.

You may also be interested in the XSelect CSH C18 VanGuard Cartridge, 130Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk, which is intended to protect all 2.1 mm and 3.0 mm I.D. XSelect CSH C18 analytical columns with sorbent particles of 3.5 m. It is possible to extend the lifetime and performance of analytical columns by eliminating particle pollution from the mobile phase stream.
What Are the Pressure and pH Recommendations for the XSelect CSH C18 Column?
The XSelect CSH C18 Column was designed to withstand pressures up to 6000 psi (415 Bar), particle sizes up to 5 µm, and pH range of 1 to 11. It is usually advisable to stay within the prescribed operational pH range to guarantee the longest possible column lifetime and effectiveness. As the temperature rises, the mobile phase and stationary phase accelerate. Higher temperatures expedite the analysis as a result.
