ABSTRACT:
A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. A temperature stabilized optical cell is disclosed which enhance consistency of response data obtained from the optical detector, especially when the use composition monitor is utilized on site.
