Abstract:
A method for monitoring ozone treatment during or after ozone processing, comprising the steps of:(a) providing a production part requiring ozone treatment and an ozone sensitive material which is capable of undergoing a physical or chemical change upon exposure to ozone into an ozone processing reactor chamber, wherein said physical or chemical change produces a visible color change of said ozone sensitive material which can be monitored during or after ozone processing; (b) introducing ozone into said reactor chamber; and (c) monitoring the color change of said ozone sensitive material and comparing the same to ozone treated standards of said same ozone sensitive material, wherein said standards have been previously treated with ozone under various reactor conditions so as to provide a spectrum of colors which can be employed to determine whether said production part has been effectively treated with ozone.
