| 摘要 |
The invention relates to an adaptation device (21) for adapting an UV- Vis cuvette (17) to perform in-situ spectroanalytical characterization of redox processes using gas species or solutes in a controlled atmosphere, said device being configured so as to fit the open end of a UV-Vis cuvette (17) intended to contain products to be measured during achievement of spectroanalytical measurements. The device comprises a main body (22) configured to form a lid covering the opened end (18) of the cuvette (17), said main body having a first part (23) and a second part (24); a working (13), a counter (14) and a reference (15) electrode with removable parts (132, 142, 52) at the respective ends of three conductors (131, 141, 151) coming from outside and passing through the main body (22); a gas inlet (16) intended to allow introduction of a gas said gas inlet having one aperture (162) directed to the working electrode (13) and second aperture (163) directed to the bottom of the cuvette, a gas outlet (27) intended to let the reactive gas in excess to flow out of the cuvette (17) and an solution inlet tube (28) for titration measurements. |
