An ion source and ion recycle module includes an electrolyte reservoir, an eluent recovery chamber, and an ion exchange connector. The electrolyte reservoir includes a chamber containing an aqueous electrolyte solution including an electrolyte having a chamber inlet and a chamber outlet, and a first electrode. The chamber inlet is fluidically connected to a source chamber of an electrolytic eluent generator and configured to receive depleted electrolyte solution from the source chamber of the electrolytic eluent generator. The chamber outlet is fluidically connected to the source chamber of the electrolytic eluent generator and configured to provide recycled electrolyte solution to the electrolytic eluent generator source chamber. The eluent recovery chamber including a second electrode and configured to receive an eluent solution including eluent counter ions from the eluent generator; and the ion exchange connector including an ion exchange membrane stack.
