ResinTech CG8-H-ID is a color-indicating 8% cross-linked gel strong acid cation resin in the hydrogen form. It is dyed with a permanent purple dye that changes from purple to amber as the resin exhausts from the hydrogen to the neutral salt form. CG8-H-ID is intended for use in applications where a visual indication of cation resin exhaustion is desired.
