Introduction

Akiyoshi Miyanaga is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of chromatographical analysis, holding 2 patents that enhance the accuracy and efficiency of anion separation.

Latest Patents

Miyanaga's latest patents include a method for chromatographical analysis of anions. This innovative method allows for the quantitative measurement of anions in an aqueous solution with high sensitivity while maintaining low electroconductivity in the eluant. The process involves connecting a separating column, a cation exchange column, and an electroconductivity detector in sequence. An aqueous solution containing an amine compound serves as the eluant, while a cation exchange column made of resin substituted with a metal ion acts as the electron acceptor.

Another significant patent focuses on the separation analysis of anions. This invention enables rapid and accurate anion separation by utilizing an electric conductivity detector integrated into a chromatographic apparatus. A binary composite solution, consisting of borax and various acids or sugars, is employed as an eluent. This method offers advantages over conventional analyses by capturing a broader range of anions with high accuracy, minimizing interference from extraneous signals due to the low conductivity of the eluent.
