Cadenza HS - C18 Direct Plasma Injection

This phase is a hybrid phase which contains both C18 and hydrophilic groups. It can be used for the direct injection of samples containing body fluids. HS-C18 exlcudes large molecules with mw > 30kD, allowing them to pass through the packed bed without being retained. Smaller compounds are then separated by the mechanism of reverse phase. Using HS-C18 means that tedious sample preparation can be avoided. Separations are rapid and retain excellent peak shape.
