Title: Fumio Masumi: Innovator in Quantitative Analysis
Introduction
Fumio Masumi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of quantitative analysis, particularly in the measurement of hydrogen peroxide. His innovative methods have implications in various enzymatic activities and analytical chemistry.
Latest Patents
Masumi holds a patent for a method of quantitative analysis of hydrogen peroxide and the reagent therefor. This method allows for high-precision analysis by reacting a divalent cobalt compound with hydrogen peroxide in the presence of peroxidase or a similar substance. The process produces a trivalent cobalt compound, which is then reacted with a trivalent cobalt indicator to create a colored complex. This complex can be subjected to colorimetric quantitative analysis, enabling the determination of enzymatic activities and the amounts of substances involved in known enzymatic reactions. The method is particularly sensitive, operating at wavelengths above 600 nm, and is free from interference by hemoglobin, bilirubin, or turbidity.
