Whatman Advanced Ion Exchange Cellulose (AIEC) products are ideal for the separation of charged biopolymers and are suitable for a wide variety of applications. Available as:

ㆍPreswollen microgranular AIEC for high load capacity, fast kinetics and resolution; saves time by eliminating the need for precycling prior to buffer equilibrium
ㆍDry microgranular AIEC for similar performance characteristics as preswollen media after precycling; reduces the possibility of bacterial growth
ㆍFibrous AIEC for maximum throughput at high flow rates
ㆍCommonly used anion and cation exchange functional groups: DEAE (diethylaminoethyl tertiary amine) and CM (ether-linked carboxymethyl)
ㆍOrthophosphate bifunctional cation exchanger for sharp separation of medium molecular weight molecules

Ion Exchange Celluloses are also available in paper format.
