phenol coefficient การใช้

• One way to compare disinfectants is to compare how well they do against a known disinfectant and rate them accordingly using the Phenol coefficient.
• To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions ( or, probably more common, dividing the dilution factor at which the tested substance shows activity by the dilution factor at which phenol shows comparable activity ).
