(A) Configuration of the sensing platform. (B) Green- and (C) Blue- component signal corresponding to the injections of 2 and 5 ppbV of NO2. The sensor probe is diethyl-p-phenylenediamine and the signal is the −log(sensing area light intensity/reference area light intensity). Flow rate = ~450 mL/min.
