COSMOSIL C18-PREP

The large particle size C18 bulk materials are widely used for lab- to process-scale purifications. COSMOSIL offers three different particle sizes of C18 packing materials.

Because reversed phase chromatography employs eluents of high viscosity such as methanol and water, the flow rate is lower than that of normal phase chromatography, which uses solvents of low viscosity such as hexane and ethyl acetate. In general, higher theoretical plate numbers can be obtained with lower flow rates.
