Premier DEAE is prepared from 10 micron particles of poly (styrene-divinylbenzene) (PSDVB) with an average pore diameter of 1000 A. Coupled to this polymer particle are chains of dimethylaminoethyl (DEAE) to produce weak anion separations over a wide pH range of 1 to 13.

Premier CM is prepared from 10 micron particles of PSDVB with an average pore diameter of 1000 A. Coupled to this polymer particle are chains of carboxymethyl (CM) to produce weak cation separation over a wide pH range of 2 to 13.
