<p>Apparatus and methods for detecting the sufficient neutralization of an oxidant disinfectant and disinfecting systems and processes which employ such apparatus and methods, detect the electrolyte characteristics of the disinfectant in a neutralizing solution. An article, such as a contact lens, is disinfected in a bath of disinfecting solution, such as a hydrogen peroxide solution. After a suitable time period in the disinfectant bath, a neutralizing agent is added to the disinfectant bath thereby forming a neutralization solution to neutralize residual disinfectant. Unneutralized residual disinfectant in a neutralization solution (e.g., in the early stages of the neutralization period) will provide the neutralization solution with electrolytic properties, including the ability to generate an electric potential. This electric potential is detected to, thereby, detect the presence of an undesired quantity or concentration of undissolved disinfectant solution in the neutralization solution. This detection is accomplished by placing electrodes in the neutralization solution and detecting the electric potential between the electrodes.</p> |
