Ion chromatography system for exchanging an ion exchanger in a suppressor and a suppressor means

摘要

An ion chromatography system having a suppressor means which is provided with a main body (4) for accommodating an ion exchanger ready for measuring; a chamber for accommodating a virgin ion exchanger (1), and an automatic exchanging means which discharges a used ion exchanger from the main body after an optional number of times of measurement and supplies the ion exchanger accommodated in the chamber to the main body. The ion chromatography system can measure a slight amount of ion species in a sample at a high sensitivity by conducting continuously a large number of times of measurement while the discharge of waste liquid can be minimized without causing a reduction of suppressing effect and a reduction of resolution performance of a desired ion species.
