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 reduced-turbulence optical detector can be used to improve collected response data. A reduced-turbulence optical detector can include a cell body disposed about a length of transparent tubing. The cell body positions one or more emitter/receiver pairs about the transparent tubing. Thus, tube junctions are eliminated and sample flow within the tube is substantially turbulence free.
