OH RADICAL DETECTION PROBE, OH RADICAL MEASUREMENT DEVICE, AND OH RADICAL MEASUREMENT METHOD
FIG3 is a flowchart for illustrating a flow of processing of an OH radical measurement method
Subsequently, an OH radical measurement method using the OH radical measurement device 100 is described. FIG3 is a flowchart for illustrating a flow of processing of the OH radical measurement method. The OH radical measurement method includes a contact step S110, an irradiation and measurement step S120, and a derivation step S130.

['5. An OH radical measurement device, comprising: an accommodation unit configured to accommodate an OH radical detection probe including an aromatic carboxylic acid, a polar aprotic organic solvent, and a polar protic organic  solvent; a gas supply unit configured to supply a gas to be measured into the accommodation unit; and a concentration conversion unit configured to convert a concentration of an OH radical in the gas to be measured based on a concentration of a reaction product of the aromatic carboxylic acid and the OH radical in the OH radical detection probe after being brought into contact with the gas to be measured.', '6. The OH radical measurement device according to claim 5, wherein the concentration conversion unit comprises: an irradiation unit configured to irradiate the OH radical detection probe after being brought into contact with the gas to be measured with UV light; a measurement unit configured to measure an intensity of fluorescence generated from the OH radical detection probe; and a concentration derivation unit configured to derive a concentration of the OH radical in the gas to be measured based on the intensity of the fluorescence measured by the measurement unit.']
