Introduction

Kazunori Tsutsui is a prominent inventor based in Osaka, Japan, known for his contributions to the field of electrophoretic measurement technologies. With a total of 8 patents to his name, Tsutsui has advanced the ways in which we measure and analyze particles in fluids, contributing to both academic research and industrial applications.

Latest Patents

Among his most recent innovations is an electrophoretic mobility measuring apparatus. This invention enhances measurement sensitivity by significantly reducing optical attenuation through the electrode face. The apparatus features a transparent electrode that forms part of a cell wall, enabling confinement of a sample while allowing incident light to pass through. A voltage is applied across the electrodes, and light scatters from the sample at a predetermined angle, with the resulting Doppler displacement measured to determine particle movement.

Another notable invention is a photon correlator designed to measure particle sizes and diffusion coefficients in real-time. It incorporates multiple sampling gates and memories, which store data on the number of photons detected over time. This mechanism allows for high-speed data processing and correlation calculations, providing valuable insights into particle behavior in various fluid conditions.
