ABSTRACT: Hydrogen
Peroxide vapour is becoming more popular to use as a method of decontamination, particularly for medical
equipment and enclosures. It is highly effective in terms of
microbiological kill rates and has a variety of uses in healthcare. Although it
is environmentally acceptable as it spontaneously decomposes into water and
oxygen, concentration of hydrogen peroxide in the air needs to be monitored and
controlled. A method of calibrating hydrogen peroxide vapor sensors is
described which is based on the concentration of hydrogen peroxide in saturated
vapour over a solution in water at a defined temperature. The saturated vapour is generated by bubbling
dry air into a solution of hydrogen peroxide
at a defined concentration and temperature. A vapour
at a concentration of 0.7 ppm was produced and used to successfully calibrate a hydrogen peroxide
sensor.
