Abstract: 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.
