HPLC Columns
Waters Corp ACQUITY UPLC CSH C18 Column, 130Å, 1.7 µm, 1 mm X 150 mm, 1/pk
ACQUITY CSH C18 columns were designed to provide alternate selectivity compared to other reversed-phase UPLC columns. These ultra-efficient columns overcome peak shape asymmetry and poor loading capacity for basic compounds, column bleed, and rapid mobile-phase re-equilibration.
Waters Corp Waters XSelect CSH C18 Column, 130Å/5μm, 19 mm × 150 mm
XSelect CSH C18 columns offer alternative selectivity for general-purpose separations. Charged Surface Hybrid (CSH) technology improves peak shape, loading for basic compounds, and mobile-phase re-equilibration. This enhances recoveries, productivity, resolution for complex samples, column lifetimes, and lowers operating costs. It supports direct scaling from UPLC/HPLC screening to lab-scale purification and is compatible with HPLC, UPLC, and UHPLC systems.

Waters Corp ACQUITY UPLC BEH C18 Column, 130Å, 1.7 µm, 3 mm X 100 mm, 3/pk
As the premier column for method development, the 1.7 um ACQUITY UPLC BEH C18 sorbent provides you with the most universal column choice for UPLC separations. The trifunctionally bonded BEH particle gives you the widest usable pH range (pH 1-12), superior low pH stability, and ultra-low column bleed for high sensitivity MS applications.
Waters Corp Waters Column, C18, 3.5 μm, 2.1 mm × 50 mm, 130 Å
This C18 column offers alternative selectivity, using CSH technology for improved peak shape, loading, reduced column bleed, and faster re-equilibration.
- Provides diverse analyte selectivity and high-resolution separations for complex samples.
- Exceptional separation performance, robustness, and throughput across HPLC, UPLC, and UHPLC.
- Superior peak shape for basic compounds, low column bleed, and ultra-efficiencies.
- Excellent batch-to-batch reproducibility for rapid method development.
- Outstanding performance, equivalent backpressure to core-shell columns, improved loading capacity and scalability.
- CSH technology enhances LC performance in acidic, low ionic strength mobile phases; non-end-capped sorbent enhances acidic compound retention.
