摘要： Embodiments provide a handheld fluorometer and method of determining a concentration of a product within a sample. In some cases the handheld fluorometer includes an immersible sensor head that measures a fluorescence of the product and a controller that calculates the concentration of product. In some cases the handheld fluorometer includes a handheld controller module, an immersible sensor head connected to the controller module, a sample cup for containing a water sample, and a fastener that removably fastens the sample cup about the immersible sensor head. In some cases the sensor head is angled with respect to the controller module and the fluorometer provides a substantially stable base. The sample cup can be removed to acquire a sample of water containing the product and then refastened about the sensor head for determining the concentration.

摘要： 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.

摘要： A microflow analytical system includes a laminate pump assembly connectable with one or more sources of fluid, one or more pneumatic control pumps, a mixer, and a sensor. The laminate pump assembly is adapted to deliver predetermined volumes of the fluid(s) through a plurality of flow paths which are formed within layers of the assembly. Each flow path can include an inlet valve, a pump valve, and an outlet valve each of which are controllable by the pneumatic control pumps. A series of manifolds can be formed within the layers of the pump assembly to provide for simultaneous activation of selected flow paths. Delivered fluid volumes can be mixed in the mixer which, in some embodiments, may be integral with the laminate pump assembly. The sensor can measure one or more characteristics of the mixed fluids to determine one or more properties of the fluids.

摘要： 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.

摘要： A fluorescence analysis system may include a sensor head that has a light source configured to emit light into a flow of fluid, a detector configured to detect fluorescent emissions from the flow of fluid, and a temperature sensor. The system may also include a flow chamber that includes a housing defining a cavity into which the sensor head can be inserted. In some examples, the housing is configured such that, when a flow of fluid enters the housing, the flow of fluid divides into at least a major stream passing adjacent the light source and the detector and a minor stream passing adjacent the temperature sensor. Such a flow chamber may direct fluid past different sensors components while inhibiting a build-up of solids particles, the generation of air locks, or other flow issues attendant with continuous or semi-continuous online operation.
