Summary
A multifunctional suppressor for both anion and cation chromatography has been designed. The suppressor comprises five thin chambers—an anion eluent suppressive chamber, a cation eluent suppressive chamber, a cathode chamber, an anode chamber, and a common electrode chamber, all of which are clipped together. An electrochemical process—electrolysis of deionized water or detector effluent—is used to regenerate the suppressor for continuous operation. Two power sources are used to supply current. The device can work as an anion suppressor, a cation suppressor, or as both anion and cation suppressors, with high suppression capacity (60 mmol L−1) and good reproducibility (RSD=0.80–0.91%) and linearity (r=0.9992).
