Waters XSelect CSH C18 Columns

Achieve unmatched reproducibility with a wide range of selectivity

Quickly and easily develop robust methods compatible with all modern chromatographic detection modes and transfer them from lab to lab with the XSelect Column family.

Designed to help you achieve reproducible and highly selective chromatographic separations, the XSelect Column family features two base particles technologies, Charged Surface Hybrid (CSH) and High Strength Silica (HSS). With XSelect Columns, method development scientists like you can achieve a wide range of selectivities across all application areas, without compromising performance.
