The utility model relates to a device for analyzing materials using ion-exchange. The utility model is provided with a cylindrical body with a five-chamber sandwich structure, wherein, electrodes are arranged at two electrode chambers at both ends of the cylindrical body; one sides of the electrode chambers are respectively provided with two suppression chambers; a common electrode chamber is arranged between two suppression chambers, and both sides of the common electrode chamber are provided with ion exchange resin membranes; one chamber outlet is connected with two chamber inlet; the chambers are filled with ion exchange resin; the first electrode chamber and the common electrode chamber, the second electrode chamber and the common electrode chamber are respectively connected with two power supplies. Due to the adoption of double suppression, suppression capacity is obviously enhanced, which is suitable for high concentration eluate and gradient wash; the structure of the cylindrical body is simplified, the membrane resistance of the cylindrical body is reduced, two currents can be respectively adjusted, and working voltages are respectively undertaken.
