Rigaku's Continued Excellence in X-ray Technology

Rigaku Corporation, a leading global provider of X-ray analysis solutions and a subsidiary of Rigaku Holdings based in Akishima, Tokyo, has made headlines by winning special awards at the Regional Invention Awards for three consecutive years. This recognition, organized by the Japan Society of Invention, underscores Rigaku's commitment to innovation and excellence in the field of X-ray analysis technology.

The latest acknowledgment is for three proprietary technologies that have reached remarkable advancements in quality control processes, particularly in the realm of alloyed galvanized steel. The company's pioneering XYZ fluorescence X-ray analysis technology allows for significantly more accurate assessment of the coating thickness and composition within the steel, which is critical for various industries including automotive manufacturing.

Innovations in Alloyed Galvanized Steel Analysis

The awarded invention, named "Fluorescence X-ray Analysis of Alloyed Galvanized Steel," utilizes two distinct optical systems with varying angles of incidence and detection. This method not only minimizes the impact of measurement depth variations but also enhances the overall accuracy of the analyses available for the entire coating layer. This innovation plays a vital role in ensuring top-notch quality control standards for alloyed galvanized steel used in car bodies and other applications.
