Title: Innovations by Sumito Ohzawa: Pioneering Techniques in X-Ray Analysis

Introduction

Sumito Ohzawa, a notable inventor based in Kyoto, Japan, has made significant contributions to the field of fluorescent X-ray analysis. With a portfolio of four patents, Ohzawa has introduced innovative methods that enhance the accuracy and efficiency of concentration measurements in various samples, including liquid fuels.

Latest Patents

His latest patents include two groundbreaking inventions. The first is a concentration measuring method and fluorescent X-ray spectrometer. This invention allows for precise analysis of liquid fuels with components such as sulfur. By subtracting the background related to scattered X-rays from the fluorescent X-ray intensity, Ohzawa’s method enables accurate correction based on the sample composition. A calibration curve is then established to calculate the concentration of the object component effectively.

The second patent pertains to a sample cell for fluorescent X-ray analysis and the associated sample cell assembly instrument. This innovative design features a sealed sample cell that adjusts its internal capacity in response to pressure changes. As the internal pressure increases, the cup end surface of the cell deforms to relieve pressure, preventing the X-ray transmission sheet from expansion, thereby ensuring the integrity and reliability of the analysis.
