OH RADICAL DETECTION PROBE, OH RADICAL MEASUREMENT DEVICE, AND OH RADICAL MEASUREMENT METHOD
FIG2 is a view for illustrating a specific configuration of an accommodation unit, a heating unit, and a gas supply unit  FIG1 is a view for illustrating an OH radical measurement device
FIG2 is a view for illustrating a specific configuration of the accommodation unit 110, the heating unit 120, and the gas supply unit 130. In FIG2, a flow of the gas to be measured is represented by the solid line arrow, and a flow of the gas after contact is represented by the broken line arrow. As illustrated in FIG2, the accommodation unit 110 is a sealed container. The OH radical detection probe 102 is accommodated in an inner space 110a of the accommodation unit 110.  FIG1 is a view for illustrating an OH radical measurement device 100. In FIG1, a flow of a gas or a liquid is represented by the solid line arrow, a flow of light is represented by the broken line arrow, and a flow of a signal is represented by the #dashed-dotted line arrow. As illustrated in FIG1, the OH radical measurement device 100 includes an accommodation unit 110, a heating unit 120, a gas supply unit 130, and a concentration conversion unit 140. Returning to FIG1, the concentration conversion unit 140 is configured to convert the concentration of an OH radical in the gas to be measured based on the concentration of a reaction product (HTA) of the aromatic carboxylic acid (terephthalic acid) and the OH radical in the OH radical detection probe 102 after being brought into contact with the gas to be measured. In this embodiment, the concentration conversion unit 140 includes an irradiation unit 150, a measurement unit 160, and a control unit 170.
