    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: 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.
