    摘要: A UV absorption spectrometer includes a housing, a controller, and a sensor unit including an ultraviolet light source, an analytical area in an analytical cell or in running water or gaseous medium, and an UV wavelength separator including a UV detector. An ultraviolet light in a wavelength range of 200-320 nm emits from the light source through the analytical area to the wavelength separator, and the controller transforms output signals from the UV detector into absorbance values or optical densities for two or more wavelengths in the wavelength range, calculates differences of said absorbance values or optical densities, determines a concentration of a chemical in the solution with calibration constants found for a known concentration of the chemical and said differences of said absorbance values or optical densities.

    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.
