Hi!
I am defining the products than they should to included in the cleaning validation process; but I have a doubt about the analysis of the worst case:
One of these products has two actives, but only one correspond to the worst case; the two actives are analysed for two differents assay methods; one method work is with HPLC (worst case) and the other one is by titration.
I have tried to change and of find an assay method for the second activo (titration), more specific (HPLC), but there isn’t, just I have find, methods that work there are methods that wear specific detectors (fluorometric, etc); the wich ones we don’t have.
To cleaning validation process. Should I consider the two actives to cleaning validation? or Should I consider just the active definite as worst case (HPLC method?
Best regards,
