What should the trial compare?
First establish the exact grade and intended use. For a permitted microbial-control application, compare the sample location, organism or biofilm evidence, water demand, contact path, pH, temperature, materials and other chemicals. Use the applicable product directions and representative evidence rather than a universal dose or contact time.
