HPLC Columns and Cartridges
Waters Corp Waters Preparative SFC Column, OBD 19 x 50 mm, 5 μm, BEH 2-EP
This column is designed for preparative Supercritical Fluid Chromatography (SFC) applications. It is suitable for preparatory scale separations and is generally used for purifying larger quantities of target compounds.
- Preparative SFC column
- BEH 2-EP (Ethylene Bridged Hybrid 2-Ethylpyridine) chemistry
- 5 μm particle size
- OBD (Optimum Bed Density) 19 x 50 mm dimensions
Waters Corp XSelect CSH C18 Column, 130Å, 3.5 μm, 3 mm X 75 mm
XSelect CSH C18 columns can be used as general purpose columns that provide alternative selectivity compared to other C18 sorbents. Charged Surface Hybrid (CSH) technology helps overcome column related problems such as peak shape asymmetry and poor loading for basic compounds, column bleed, and slow mobile-phase re-equilibration.

Waters Corp Viridis CSH Fluoro-Phenyl OBD Prep Column, 130Å, 5 µm, 30 mm X 50 mm, 1/pk
Designed and tested for SFC, the Viridis 5 µm columns demonstrate a wide range of selectivity for greater resolution. The reduction and control of surface silanol activity on Viridis Hybrid particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
