  • Publication number: 20090150106
    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 used to determine the concentrations of peracid and/or peroxide in the use composition based upon an evaluation function determined by a calibration method. The calibration method includes determining coefficients of the evaluation function based upon known concentrations, and measured response data of calibration samples.

  • Publication number: 20090097029
    Abstract: An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium.

  • Publication number: 20080030712
    Abstract: An ultraviolet (UV) fluorometric sensor measures a chemical concentration in a sample based on the measured fluorescence of the sample. The sensor includes a controller, at least one UV light source, and at least one UV detector. The sensor emits UV light in a wavelength range of 245-265 nm from the light source through the sample in an analytical area. The UV detector measures the fluorescence emission from the sample. The controller transforms output signals from the UV detector into fluorescence values or optical densities for one or more wavelengths in the wavelength range of 265-340 nm. The controller calculates the chemical concentration of the chemical in the sample based on the measured fluorescence emissions.

  • Patent number: 7044662
    Abstract: An apparatus for developing a polymeric film without the need for a water rinse step is disclosed. An object having a surface supporting a polymeric film is placed onto a support region within a pressure chamber of the apparatus. A fluid and developer is introduced into the pressure chamber and the object is processed at supercritical conditions to develop the polymeric film such that the polymeric film is not substantially deformed. The pressure chamber is then vented.

  • Patent number: 6928746
    Abstract: A method for drying an object, having a polymeric film, wherein the object is submerged in a rinse liquid. The object is removed from the rinse liquid and the object is placed in a solvent bath before a sufficient amount of the rinse liquid can evaporate from the object. The density of a solvent in the solvent bath depends on a direction of orientation of the polymeric film with respect to a force. The object is removed from the solvent bath. A drying process is performed.
