The 6 cc cartridges contain a novel, mixed-mode polymeric sorbent optimized for higher selectivity and sensitivity in extracting basic compounds with cation-exchange groups. This sorbent is water wettable, maintaining higher retention and excellent recoveries even if the sorbent runs dry, eliminating the need to prevent sorbent beds from drying out before sample loading.
