XSelect HSS and CSH XP Columns

Unmatched Selectivity Choice

XSelect eXtended Perfomance (XP) Columns provide the most diverse selection of sorbents for ultra-high performance (UHPLC) separations. The HSS (High-Strength Silica) and CSH (Charged-Surface Hybrid) base particles provide separation scientists with uniquely selective columns that deliver operational stability and method scalability for UPLC, UHPLC and HPLC separation platforms.

Diverse Retention Characteristics

Method development scientists use selectivity and retentivity to influence chromatographic behavior. The selection of phases in the XSelect family offers the ability to achieve selectivity and retention of a wide variety of compounds without compromising performance attributes such as superior peak shape for basic compounds, low column bleed, excellent batch-to-batch reproducibility or high efficiency.

Maximum Column Performance

When used on low dispersion UHPLC instrumentation, XSelect eXtended Perfomance (XP) columns improve system performance by decreasing peak width and increasing peak height with the result of maximizing analyte sensitivity. All XSelect HSS and XSelect CSH XP columns are designed to be stable at high operational backpressures to allow faster flow rates to accelerate sample throughput.

Minimal chromatographic effects with VanGuard

VanGuard Column Protection

The often complex sample matrices encountered in pharmaceutical, natural product, environmental, and industrial chemical analysis prematurely shorten analytical column lifetime and degrade chromatographic performance. Waters VanGuard Cartridge Columns help improve analytical column performance by removing particulate and chemical contamination that may be present in the mobile-phase stream—without compromising chromatographic performance.
