Methods and systems are disclosed for analyzing and treating a fluid containing a peroxyacid and/or peroxide. A method of analyzing the fluid includes introducing into the fluid a decomposition agent that catalyzes decomposition of the peroxyacid and/or peroxide into decomposition products including oxygen, then directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent, and determining an amount of the peroxyacid and/or peroxide present in the fluid. The amount of peroxyacid and/or peroxide in the fluid can also be monitored and controlled by further adjusting the amount of the peroxyacid and/or peroxide in the fluid based on the determined amount thereof. A system for performing the methods includes a decomposition agent infusion device for introducing the decomposition agent into a fluid sample, and a sensor for directly or indirectly measuring an amount of oxygen produced after introduction of the decomposition agent.

The invention relates to methods, compositions and kits for determining the cleanness of a surface. Described herein is a kit for determining the cleanness of a surface comprising an enzymatic solution comprising catalase; and a developer solution comprising hydrogen peroxide. Described also is a method for determining the cleanness of a surface comprising: applying on a zone of a surface to be cleaned an enzymatic solution comprising catalase and letting it dry; after cleaning said surface, applying on said zone a developer solution comprising hydrogen peroxide; and detecting a catalytic reaction between remaining catalase and hydrogen peroxide, wherein presence of a catalytic reaction is indicative of a surface not properly cleaned. Also provided are specific enzymatic solutions and developer solutions for the kits and methods.
