Available CHROSPE Phases
CHROSPE cartridges come in two pressure ranges (described above), and six main phase categories, to accommodate the widest possible range of applications; these categories include non-polar, polar, cation-exchange, anion-exchange, and two mixed-mode categories (cation-exchange/non-polar, and anion exchange/non-polar). Some of these phases may be used in more than one chromatographic mode depending on the solvent environment (for example, C2 and CN phases may be used in either non-polar or polar extraction modes). Other phases – such as the mixed mode phases - are specifically designed to be used in more than one mode, for enhanced selectivity and cleaner sample extracts.
Details of the different sorbent chemistries are as follows:
