摘要： A kit and method for accurately determining the concentration levels of peracetic acid in a solution containing a peroxide or other oxidant is disclosed. In order to determine the concentration of peracetic acid in the solution, a pH buffer system is used to deactivate high levels of a peroxide in a disinfectant solution without interfering with active peracetic acid levels in the solution. At least one test strip is used to measure the peracetic acid concentration in the solution. A test vial for combining the solution with the pH buffer prior to contact with the test strip is provided.
