VORRICHTUNG ZUM SPEKTRALPHOTOMETRISCHEN DOSIEREN VON WÄSSERIGEN FLÜSSIGKEITEN

摘要

Method and apparatus for the spectrophotometric assay of aqueous liquids are provided with a pump for aspirating liquids, a filter with two outlets for filling a cell in which the interferometric measurements are made at a temperature between 35 and 50 DEG C. at a maximum fluctuation of 0.2 DEG C., and with a maximum relative humidity of 0.2%. Absorption curves A(f) are determined with respect to a matrix and the concentrations of components to be assayed are calculated by the use of standard equations.
