Additional Information
XSelect CSH Phenyl-Hexyl VanGuard Cartridge, 130Å, 3.5 µm, 3.9 mm X 5 mm, 3/pk XSelect CSH Phenyl-Hexyl VanGuard Cartridges are intended to enhance the lifetime and performance of XSelect CSH Phenyl-Hexyl Analytical columns by eliminating particle pollution from the mobile phase stream. This cartridge has been designed to protect all 4.6 mm I.D. 3.5 µm sorbent particles in XSelect CSH Phenyl-Hexyl analytical columns. The XSelect CSH Phenyl-Hexyl Column offers superior separation performance, resilience, and throughput for HPLC tests while being fully compatible with all HPLC, UPLC, and UHPLC technologies. The XSelect CSH Phenyl-Hexyl Column outperforms core-shell columns in terms of performance and backpressure. Furthermore, the analytical column outperforms fully porous particle columns in terms of loading capacity and particle size scalability. The XSelect CSH Phenyl-Hexyl Column incorporates Charged Surface Hybrid (CSH) technology, which greatly improves all areas of liquid chromatography performance in acidic, low ionic strength mobile phases.

FAQ
What Justifies the Need for a Gradient System? To improve chromatographic separations, gradient systems allow you to adjust the flow rate and solvent/buffer changes. They can also be employed to sharpen separations and speed up column re-equilibration. When equipped with methanol, acetonitrile, ammonium acetate buffer, and formic acid solution, a four-solvent gradient system is useful for method development. For quick separations, quality control laboratories frequently employ isocratic systems that operate a constant-composition premixed mobile phase.
