CLEAN SCREEN® DAU is a copolymerized sorbent, utilizing both a reverse (C8) phase and an ion exchange (benzenesulfonic acid) phase bonded to the same particle. The mixed-mode nature allows for maximum selectivity for the extraction of acids, neutrals, and bases. This flexibility and versatility are ideal for both screening and confirmation analyses of virtually all drug categories.
