Abstract
A wet chemical indicator for peracetic acid solutions includes an indicator for peracetic acid and an inhibitor. The inhibitor is selected to inhibit a selected peracetic acid concentration in a reproducible sample of a solution containing peracetic acid. The indicator exhibits an observable change when the selected concentration of peracetic acid is exceeded. In this manner, a rapid indication of whether the peracetic acid solution is of a required minimum strength is provided.
