Decolorimeter
A decolorimeter or decolorimeter ( French : décolorimètre) is a measuring instrument for determining the decolorizing capacity of decolorizing agents such as charcoal . It was used especially in sugar manufacturing .
It was invented by the French chemist Anselme Payen , who dealt with the analysis, decolorization, bleaching and crystallization of sugar. Payen used animal charcoal to decolorize the sugar solutions, and he developed the decorative colorimeter to determine the degree of decolorization. Payen first published his research and results in the field of sugar decoloration in 1822 .
