Information on the Measurement of Hydrogen Peroxid and Peracetic Acid
The methods of determination of hydrogen peroxide and PAA are not continuous measurements methods, but methods whereby the concentration is measured for samples taken at certain times.
These analytical methods are laboratory procedures requiring a considerable outlay in personnel and time.
In order to regulate the concentration of a disinfectant, it is advantageous if a electrical signal is available that is continuous and proportional to the concentration of disinfectant. This signal can then be used as the input signal for controlling a disinfectant metering system, i.e. the concentration can be completely automatically regulated.
A membrane-covered amperometric measuring cell can be used for monitoring the peracetic acid concentration and the concentration of hydrogen peroxide.
