ABSTRACT:
As used to provide an effluent, from which ion-exchange capacity of a sample of a selected type of ion-exchange resin can be determined analytically, an apparatus comprises a column, which is adapted to contain the sample, a solenoid valve, which controls an effluent from an outlet of the column, a solenoid valve, which when opened allows a regenerating agent to flow into an inlet of the column, a solenoid valve, which when opened allows a rinsing agent to flow into the inlet of the column, a solenoid valve, which when opened allows an exhausting agent to flow into the inlet of the conduit, and electronic sequencing means, which operates sequentially for certain specified functions involving the solenoid valves.
