Dionex™ CRD 180, 200 and 300 Carbonate Removal Device

Improve sensitivity and increase linearity range of your ion chromatography (IC) applications by removing carbonate from the suppressed eluent stream. The Thermo Scientific™ Dionex™ CRD 180, 200 and 300 Carbonate Removal Devices support the removal of carbonate by diffusion through the walls of a carbonate-selective, gas-permeable membrane. The Dionex CRD 300 was designed for use with carbonate eluent-based chemistries, while the Dionex CRD 180 and 200 were designed for use with hydroxide- and borate-based chemistries.
