Purolite® PCR642Ca
SAC GEL - CHROMATOGRAPHIC
GRADE, CA++
Purolite PCR642Ca is a strongly
acidic gel-type cation exchange resin with
a polystyrenic matrix which offers separation
of both polar and in certain cases, non-polar
chemical compounds. High speed efficient
separation is achieved even for compounds
of higher molecular weight as a result of
its special bead distribution, high moisture
content, and excellent mechanical strength.
It is one of a range of Purolite "Separlite"
ion exchange resins. Purolite "Separlite"
ion exchange resins for chromatography are
high quality crosslinked poly(styrene)-based
cation and anion exchangers with closely
sized spherical bead form, suitable for
separations which depend on relatively small
differences of affinity of the materials
being chromatographed. They are designed
mainly for use in ion exchange columns and
industrial plant. They are not for capillary
use in e.g. HPLC equipment.
