Introduction

Michio Butsugan is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of supercritical fluid extraction, holding a total of five patents. His work focuses on improving extraction methods and materials used in chromatography.

Latest Patents

One of his latest patents is an extract recovery method and analysis method using polymer beads in a trap during supercritical extraction. This innovation addresses issues such as prolonged extraction times and undesired elution of target components. The method involves storing a sample in a container upstream of a back-pressure control valve. A mixed fluid of carbon dioxide in a supercritical state and a modifier is introduced into the container to extract components from the sample. The extracted components are then collected in a trap column filled with polymer beads, ensuring secure collection even with increased modifiers in the supercritical fluid.

Another significant patent involves a column packing material for supercritical fluid chromatography. This material allows for good peak shape during the analysis of free fatty acids and agricultural chemicals. It demonstrates excellent durability for repeated analyses and includes polymer particles with specific swelling characteristics after absorbing solvents.
