PROBLEM TO BE SOLVED: To provide an electrochemical microcell to be used in a high-temperature site, a high-pressure site, and a high-temperature-pressure site.SOLUTION: A heat-resistant, pressure-resistant, and corrosion-resistant electrochemical microcell comprises: an electrode provided at its end with a cone taper; an electrode adaptor in which the electrode is to be fitted, the electrode adaptor having a pressure-resistant sealing fitting face on which the cone taper of the electrode is to be fitted; a first pipe provided at its end with a cone taper; a pipe adaptor in which the cone taper of the first pipe is to be fitted, the pipe adaptor having a sealing fitting face on which the cone taper of the first pipe is to be fitted; and a cell body including a recessed portion having a fitting face on which each of fitting faces provided at the back of the electrode fitting portion of the electrode adaptor and the pipe fitting portion of the pipe adaptor is to be fitted and a microchannel. The electrode includes a second pipe, an electrode fine wire provided in the second pipe, and a metal oxide insulation layer provided between the second pipe and the electrode fine wire. The microchannel has an inner diameter of 1.0 mm or less, and the electrode fine wire in the electrode has an outer diameter of 1.0 mm or less. The heat-resistant, pressure-resistant, and corrosion-resistant electrochemical microcell performs electrochemical measurement in a field of fluid that flows into the microchannel from the outside through the first pipe. |
