Electrolytic remote ion source and ion recycle (ISIR) module

An electrolytic eluent generator system comprising:

• an electrolytic eluent generator including:
• an electrolyte reservoir including:
• a first chamber containing an aqueous electrolyte solution, the first chamber including a first inlet and a first outlet;
• and
• a first electrode;
• an eluent generation chamber including a second electrode;
• and
• a first ion exchange connector including a first ion exchange membrane stack, the first ion exchange connector between the electrolyte reservoir and the eluent generation chamber;
• an ion source and ion recycle module including:
• a second electrolyte reservoir including:
• a second chamber containing the aqueous electrolyte solution including an electrolyte, the second chamber having a second chamber inlet and a second chamber outlet, the second chamber inlet fluidically connected to the first outlet of the first chamber, the second chamber inlet configured to receive depleted electrolyte solution from the first chamber, the second chamber outlet fluidically connected to first inlet of the first chamber, and the second chamber outlet configured to provide recycled electrolyte solution to first chamber;
• and
• a third electrode;
• an eluent recovery chamber including a fourth electrode and configured to receive an eluent solution including eluent counter ions from the eluent generator;
• and
• a second ion exchange connector including a second ion exchange membrane stack, the second ion exchange connector coupling the second electrolyte reservoir and the eluent recovery chamber;
• and
• a pump configured to circulate the aqueous electrolyte solution between the first chamber of the first electrolyte reservoir of the electrolytic eluent generator and the second chamber of the second electrolyte reservoir of the ion source and ion recycle module.
