Chromalite 15AD2Q is a quaternary ammonium functionalized, highly crosslinked, highly porous polymer. Available in small, uniform particle sizes, Chromalite 15AD2 is ideal for IEX high pressure liquid chromatography (IEX-HPLC).  The spherical beads show exceptional batch-to-batch consistency, enabling simple scale-up from laboratory analyses through to full-scale plant operation. Chromalite AD is manufactured using our patented seeding technology.

Equivalent to Dow XT30
