Electrochemically generated multifunctional suppressor for ion chromatography
- 化学化工－已发表论文 
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).
