A method of assessing the presence of ozone consuming agents on the surface of an object or within an enclosed volume, by providing a fluid containing ozone, bringing the fluid into contact with the object or introducing the fluid into the enclosed volume, measuring the concentration of ozone in the fluid and evaluating the presence of the ozone consuming agents as a function of the measured ozone concentration. In particular the method is applicable as a method of assessing the cleanness, expressed in terms of the essential absence of ozone consuming agents, of a surface or volume. A device for use in the method, comprising at least one source of a fluid containing ozone, means for bringing the fluid into contact with the object or introducing it into the enclosed volume, and means for measuring the ozone concentration in the fluid. Fields of application are found e.g. within the medical, pharmaceutical and food production industry. |
