Abstract:

Mist streams comprised of H 2O 2/H 2O droplets are a recent innovation for disinfecting medical equipment, but the availability of a sensor that could monitor the concentration of H 2O 2 applied during the treatment would be desirable. Here we describe a means to obtain a rapid estimation of H 2O 2 concentration in this environment. The proposed sensor is based on a platinum resistance thermometer coated with a layer of MnO 2 catalyst. It may be calibrated to operate either during the mist delivery step of a disinfection cycle, or during the evacuation (drying) phase. Cooling of the sensor surface due to evaporation of H 2O} and effervescence of decomposing H 2O 2 operates against heat generated by the decomposition reaction to produce a well-defined minimum in the temperature. The time and temperature at which this minimum occurs are well correlated, with the H 2O 2 content of the solution used to produce the mist droplets. © 2012 IEEE.
