Title:
ION CHROMATOGRAPH
Document Type and Number:
WIPO Patent Application WO/2016/098260
Kind Code:
A1
Abstract:
The present invention reduces the effect, on a detector, of flow pulsation resulting from gas generated in an electrodialytic suppressor, even when a voltage is being supplied to the electrodialytic suppressor. Eluent that has passed through a separation column and an eluent flow path of the electrodialytic suppressor is fed to the detector. After passing through the detector, the eluent is supplied to an electrode-liquid flow path of the electrodialytic suppressor through an electrode-liquid pipe. In the electrode-liquid flow path of the electrodialytic suppressor, oxygen and hydrogen are generated by electrolysis of water. At an intermediate point in the electrode-liquid pipe, a flow-pulsation reducing device is provided. The flow-pulsation reducing device reduces flow pulsation resulting from bubbles generated in the electrode-liquid flow path of the electrodialytic suppressor.
