ResinTech CG8-H-BL-SC is an 8% cross-linked gel strong acid cation resin in the hydrogen form. It has been functionally tested to produce >18 megohm resistivity and under 50 ppb of TOC (in a mixed bed using SC grade anion resin). CG8-H-BL-SC is intended for use in industrial applications where a hydrogen form cation resin is required and for mixed beds where its dark color makes visual identification of the cation/anion interface plainly evident.
