I was tasked to create a verification plan for the cleaning chemicals. Below are the points provided my immediate superior:
a) Identify the receiving parameters for the following:
1) Isopropyl / Ethyl alcohol (parameter that can represent that the solution is 70%)
3) Quaternary Ammonium compound
4) Sanitizers (Alcohol Based)
b) Verification for effectiveness (microbiological test)
I have no problem with verification of effectiveness. We are doing %kill analysis to identify the log reduction when the chemical is applied to a culture of bacteria.
The problem is how can I determine receiving parameters for the above mentioned chemicals?
Some of my colleagues suggested pH determination but when I checked the pH of 70% and 95%alcohol pH value difference is not significant. Looking forward to your help and suggestions if there are available tools/kits/methods to verify the concentration during receiving.
