Abstract:
1. A method of simultaneous anion suppression and cation suppression, using a continuous electrolytic ion exchange device, comprising: (a) flowing a basic solution containing an anion sample of interest through a homogeneous cation depletion chamber of said continuous electrolytic ion exchange device to suppress said basic solution by way of cation exchange occurring on cation exchange material in said homogeneous cation depletion chamber, wherein said cations are transferred from said homogeneous cation depletion chamber to a heterogeneous anion and cation concentration chamber of said continuous electrolytic ion exchange device; and (b) simultaneously flowing an acidic solution containing a cation sample of interest through a homogeneous anion deletion chamber of said continuous electrolytic ion exchange device to suppress said acid solution by way of anion exchange occurring on anion exchange material in said homogeneous anion depletion chamber, wherein said anions are transferred from said homogeneous anion depletion chamber to said heterogeneous anion and cation concentration chamber of said continuous electrolytic ion exchange device; and
