Waters, 186006622, Viridis HSS C18 SB Column, 100Å, 1.8 µm, 3 mm X 75 mm, 1/pk

Designed and tested for the ACQUITY UPC2 system, the Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.

Additional Information
Viridis HSS C18 SB Column, 100Å, 1.8 µm, 3 mm X 75 mm, 1/pk The Viridis sub-2-µµm and 3.5-m columns, which were developed and tested specifically for the ACQUITY UPC2 system, have exceptional efficiency and resolution. Under SFC conditions, the decrease and control of surface silanol activity on Viridis particles generates good peak morphologies even for well-retained basic achiral compounds — without the use of mobile-phase additives. Viridis Columns have achiral SFC selectivities as an added bonus. These columns are made with patented Ethylene Bridged Hybrid (BEH) particle technology, Charged Surface Hybrid (CSH) particle technology, and High-Strength Silica (HSS) particle technology. The decrease and control of surface silanol activity on Viridis particles gives excellent peak geometries under SFC predictions, even for well-retained basic achiral chemicals. The Viridis Silica columns, such as the Viridis HSS C18 SB Column, are designed to be exceptionally repeatable and predictable, with strict product criteria and low metal content, and are based on Waters' rich history of chromatographic silica manufacturing. They are available for both analytical and purification preparative column dimensions. It is commonly used in archival SFC separations, both with and without additives, displaying good retention, peak shape, and selectivity.

FAQ
Is It Possible To Use Water As A Mobile Phase? Because of the change in dielectric constant, pure water at a high temperature can be employed as a mobile phase in liquid chromatography. Because water behaves as an organic solvent, its dielectric constant decreases from 85 at 25°C to 35 at 200°C.
