Introduction

Yusuke Masuda is an inventor associated with Kyoto, Japan, and Shimadzu Corporation. His patent work concerns a method for analyzing carboxylic acid anhydrides and related compounds using supercritical fluid chromatography.

Latest Patents

Masuda is credited with 1 patent: “Analysis Method of Carboxylic Acid Anhydride.” The method analyzes a sample in two ordered stages. First, the sample passes through a column with a mobile phase made from carbon dioxide and an organic solvent without a hydroxyl group, allowing a carboxylic acid anhydride to be detected. After the anhydride’s retention time has elapsed, the mobile phase is switched to a mixture of carbon dioxide, an acid, and an organic solvent with a hydroxyl group. This second stage detects at least one carboxylic acid ester or carboxylic acid eluted from the column.

Career Highlights

Masuda’s listed patent reflects work on analytical methods that use different mobile-phase compositions to detect multiple types of compounds in a sample. He is associated with Shimadzu Corporation, a company known for analytical and measurement technologies.
