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： 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 and detectors detect transmitted light at a plurality of wavelengths. The output of each detector and combinations of outputs of multiple detectors are associated with at least one out-of-product threshold. In addition, a color ratio is established. A controller compares the detector outputs and combination outputs with the associated out-of-product threshold(s). If any of the thresholds are satisfied, the controller compares the color ratio with an associated out-of-product threshold to verify an out-of-product event has occurred and reduce errors due to batch-to-batch variation of the product. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.

摘要： An apparatus, method and system providing for calibration and/or control of a liquid dispensing system is disclosed. The hand-held calibration auditing tool includes a flow meter (36-37) with inlets adapted for quick connection to one or more liquid inputs to a liquid dispensing system (10). A sensor (94-95) having a data output of liquid flow information for a liquid input to the dispensing system (10) is operably connected to a controller (12) to receive the liquid flow information for the liquid input. The controller (12) provides a dilution rate and other liquid flow information for a liquid product input to a dispenser.

摘要： An optical sensor may include a sensor head that has an optical window for directing light into a flow of fluid and/or receiving optical energy from the fluid. The optical sensor 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 flow chamber includes an inlet port defining a flow nozzle that is configured to direct fluid entering the flow chamber against the optical window of the sensor head. In operation, the force of the incoming fluid impacting the optical window may prevent fouling materials from accumulating on the optical window.

摘要： Some embodiments provide methods for calibrating a fluorometer in order to account for one or more optical properties of a water sample affecting fluorescence measurements. In some cases one or more calibration solutions are prepared with sample water from a specific field site. Fluorescence measurements are taken from a water sample and one or more of the calibration solutions, and calibration parameters are determined based on the measurements. In some cases a calibration solution is prepared by spiking sample water to include a higher concentration of a fluorescent tracer and measurements are taken to characterize a calibration slope coefficient. In some cases a calibration solution is prepared by adding an acid and measurements are taken to characterize a background fluorescence in the sample.
