PROBLEM TO BE SOLVED: To implement automatic or simple operation for exchanging material that captures dispersed salt contents, so as to store used material in a manner where salt contents having different capture period are not mixed.SOLUTION: A holding device 100 comprises a housing 130 in which openings 133A, 133B are disposed for exposing a part of a dispersed salt content capturing member 20 and in which an upper stage portion 131 and a lower stage portion 132 are disposed respectively upper side and lower side of the openings, a lower stage cartridge 122 that takes up and holds unused parts of the dispersed salt content capturing member 20, an upper stage cartridge 112 that takes up and holds used parts of the dispersed salt content capturing member 20 being taken out from a lower stage holding part 120 and passing the positions of the openings 133A, 133B, and a film cartridge 114 that is disposed at the upper stage portion 131 and takes up and holds a film F. The upper stage cartridge 112 overlays the film F taken out from the film cartridge 114 with the used parts of the dispersed salt content capturing member 20 so as to take up and hold them. |
