  • Patent number: 8076155
    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. Response data obtained by the detector is indicative of the optical absorbance of the sample mixture as a function of time. A processor analyzes the response data to determine a corresponding best fit linear relationship. Depending upon an expected concentration range, the initial absorbance and/or the slope of the best fit equation are used to calculate the concentrations of the peracid and peroxide in the use composition.

  • Patent number: 7531365
    Abstract: Described is apparatus and a process for the enablement of functional product analysis of the headspace proximate one or more substrate, such as hair, fabric or skin, surfaces having affixed thereto functional product, a fragrance composition and/or malodor counteractant composition-containing microcapsules. The apparatus employs mobile microcapsule-abrading solid objects, including agitating stainless steel spheres during analyte collection in a gas-flow/trapping tube analyte collection apparatus. The reciprocating motion and the air-flow are commenced simultaneously thereby enabling the solid objects to become mobile and to effectively abrade the microcapsules affixed to the semi-solid surfaces.

    Abstract: A portable multi-channel device for optically testing of a liquid sample includes a controller; and a sample holder with a cylindrical sample compartment and at least two optical channels respectively for measuring turbidity of the sample liquid and for measuring one other optical property of the sample liquid. Each of the optical channels including: a light source placed at one end of the channel, a main detector placed across the sample compartment from the light source, a reference detector for measuring an intensity of light emitted by the light source, and an excitation focusing optic for directing a light emitted by the light source through the sample compartment towards the main detector. Signals from the reference detector of the channel, the main detector of the channel, and another main detector of another channel perpendicular to the channel are processed by the controller to evaluate the turbidity of the liquid sample.
