PRETREATMENT DEVICE FOR ANALYSIS OF DISSOLVED ION, DISSOLVED ION ANALYSIS SYSTEM, AND PRETREATMENT METHOD FOR ANALYSIS OF DISSOLVED ION
|
| Abstract | Provided is a pretreatment device for use in the analysis of a dissolved ion, which enables the separation of a dissolved ion to be analyzed from a sample solution within a short time and which is applicable to both a case in which the dissolved ion to be measured is a cation and a case in which the dissolved ion to be measured is an anion. A pretreatment device (10) for use in the analysis of a dissolved ion, which comprises: a sample solution flow path (11) through which a sample solution containing the dissolved ion to be measured flows; an extracted solution flow path (13) which is arranged adjacent to the sample solution flow path (11) so as to intercalate a dialysis membrane (12) between the extracted solution flow path (13) and the sample solution flow path (11); a pair of electrodes (14a, 14b) which are so arranged as to intercalate the sample solution flow path (11) and the extracted solution flow path (13) therebetween; and a direct current power source (5) which enables the generation of a predetermined potential difference between the electrodes (14a, 14b). When the pretreatment device (10) is used, it becomes possible to separate a dissolved ion to be analyzed from a sample solution within a short time, and the device (10) is effective for a pretreatment in the analysis of an ion, such as an ion chromatography method, an ICP emission spectrometry method, an atomic absorption spectrometry method and a mass spectrometry method. |
