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