Waters, 186004749, XSelect HSS C18 SB Column, 100Å, 3.5 µm, 4.6 mm X 150 mm, 1/pk

The HSS C18 SB (Selectivity for Bases) is an unendcapped, low-coverage C18 bonded-phase column that was designed specifically to provide increased silanophilic interactions. This results in an alternate selectivity compared to a high-coverage fully-endcapped C18 column, particularly for basic compounds.

Additional Information
XSelect HSS C18 SB Column, 100Å, 3.5 µm, 4.6 mm X 150 mm, 1/pk XSelect HSS C18 SB Columns are designed to work especially well with complex mixtures of basic and non-basic compounds over low pH separations. The HSS C18 SB 'Selectivity for Bases' is an un-end-capped, low-coverage C18 bonded-phase column built to provide increased silanophilic interactions. This feature enables the column to have an alternate analyte selectivity compared to high-coverage, fully end-capped C18 Columns with stationary phases. The XSelect HSS C18 SB Column would be an excellent addition to your lab, as you can achieve the best separation and overcome chromatography challenges. A single particle substrate is not enough to meet all the chromatographic challenges, so Waters offers chromatographers a broad range of lab equipment, including unique columns with carefully chosen ligands combined with proprietary Charged Surface Hybrid (CSH) and High Strength Silica (HSS) Technologies to deliver operational stability. The XSelect HSS C18 SB Column is based on HSS (High Strength Silica), which Waters developed to complement the chromatographic performance of BEH (Ethylene Bridged Hybrid) and CSH (Charged Surface Hybrid) particles. Designed to withstand the UPLC pressures, the XSelect HSS C18 SB Columns are fully scalable and transferable to UPLC separations and offer chromatography-specific advantages such as increased polar compound and different selectivity.
