Pretreatment device for dissolved ions analysis and dissolved ion analysis system

摘要

A pretreatment device 10 for analysis of dissolved ions, which comprises: a sample solution flow channel 11 through which a sample solution containing dissolved ions flows; an acceptor solution flow channel 13 which is arranged adjacent to the sample solution flow channel 11 so as to intercalate a dialysis membrane 12 between the acceptor solution flow channel 13 and the sample solution flow channel 11; a pair of electrodes 14a, 14b which are so arranged as to intercalate the sample solution flow channel 11 and the acceptor solution flow channel 13 therebetween, wherein one of the pair of electrodes 14a, 14b is provided on the sample solution flow channel 11, and the other one of the pair of electrodes 14a, 14b is provided on the acceptor solution flow channel 13; a direct current power source 5 which enables the generation of a predetermined potential difference between the electrodes 14a, 14b; and an electrode separator 15 provided between the dialysis membrane 12 and an inside surface of the electrode provided on the acceptor solution flow channel 13.
