摘要:
A system for generating a high purity eluant that can be used in detecting sample ions comprises: a water source, an eluant generating source, and a fluid flow path that is in fluid communication with the water source, wherein the fluid flow path is the only path for liquid flow through the eluant generating source. By electrolysis of water and combining electrolysis ions with counter ions of a sample a high-purity eluant is formed.

摘要:
A method of detecting analyte ions by continuous electrochemically suppressed ion chromatography comprising: (a) flowing analyte ions in an aqueous mobile phase comprising electrolyte through an analytical column separating means to form an aqueous chromatography effluent comprising separated analyte ions and electrolyte; (b) flowing the aqueous chromatography effluent through a suppressor means for splitting the chromatography effluent into a first chromatography effluent flow stream and a second chromatography effluent flow stream; (c) applying an electrical potential in the suppressor means such that electrolyte is electrochemically driven into the first chromatography effluent stream and away from the second chromatography effluent flow stream; (d) flowing the second chromatography effluent flow stream out of the suppressor means; (e) detecting the analyte ions in the second chromatography effluent flow stream.
摘要:
A method of detecting sample ions in an aqueous mobile phase comprises flowing the sample ions and the mobile phase through a stationary phase and applying an electrical potential across an ion exchange packing material includec in the stationary phase to thereby initiate electrolysis of water. The stationary phase is then, at least partially, regenerated by flowing of the electrolysis ions across the stationary phase. In a further aspect, the stationary phase is at least partially regenerated in the presence of sample ions.
