Claim:
1. An electrodialytic buffer generator comprising: (a) a flow-through central buffer-generating channel comprising a first electrode, having an inlet and an outlet; (b) a second chamber comprising a second electrode, (c) a third chamber comprising a third electrode, (d) a cation exchange barrier, capable of passing cations but not anions and of blocking bulk liquid flow, disposed between said second chamber and said buffer-generating channel; and (e) an anion exchange barrier, capable of passing anions but not cations and of blocking bulk liquid flow, disposed between said third chamber and said buffer-generating channel, wherein a chromatography column is in fluidic communication with said electrodialytic buffer generator and disposed downstream of said electrodialytic buffer generator.
