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.

An electrochemical sensor for the detection and analysis of an analyte in a solution is disclosed. The electrochemical sensor has an electrically non-conductive support; a plurality of electrodes on the support, each electrode formed from an electrode material and having a first surface and an opposite second surface, said first surface facing towards the support and the second surface facing away from the support. The plurality of electrodes includes a reference electrode, a counter electrode, and a working electrode. The working electrode has a reagent composition containing a reagent for detecting an analyte applied directly to the second surface of the working electrode or dispersed throughout the electrode material of the working electrode.
