ION CHROMATOGRAPH

摘要

A suppressor is structured by an ion exchange section being structured by an eluate path forming member forming an eluate path and a regenerant path forming member forming a regenerant path being stacked across an ion exchange film, and a heat-conductive heat block covering the outside of the ion exchange section. A separation column, the suppressor, and an electrical conductivity meter are accommodated in a common constant temperature bath. The inside of the constant temperature bath is feedback-controlled by a temperature control section so as to be maintained at constant temperature.

1. An ion chromatograph comprising:
a separation path including a separation column for performing separation of an ion component in a sample; a measurement path including an electrical conductivity meter for measuring electrical conductivity; and a suppressor including an eluate path, connecting between the separation path and the measurement path, for passing an eluate from the separation column, a regenerant path, arranged facing the eluate path, for passing a regenerant, and an ion exchange film, interposed between the eluate path and the regenerant path, for causing ion exchange to be performed between the paths, the suppressor being for suppressing background electrical conductivity of the eluate from the separation column, wherein the suppressor is structured by an ion exchange section structured by an eluate path forming member forming the eluate path, the ion exchange film, and a regenerant path forming member forming the regenerant path being stacked with one another, and a heat-conductive heat block covering the ion exchange section, and wherein the electrical conductivity meter and the suppressor are accommodated in a common constant temperature bath.
