Mass Spectrometry Group

With the keyword of “Render visible the previously invisible”, our group develops original and cutting-edge mass spectrometers and conducts original research using these instruments.
The mass spectrometry group has a long history since the development of Japanese first mass spectrometer in the late 1930s. Recently, we have developed a compact, high-resolution multi-turn time-of-flight mass spectrometer and an imaging mass spectrometer, and are engaged in cross-disciplinary research using these instruments.

  • 2023.10.1 Toyoda Laboratory has become a member of the Cooperative Division for the Department of Chemistry. We now belong to both the Department of Physics and the Department of Chemistry. As a result, we are now able to further promote interdisciplinary and cross-disciplinary research.

To students who wish to join Toyoda Laboratory

The Toyoda Laboratory develops novel mass spectrometers and related technologies, and conducts various researches using the developed instruments. Mass spectrometry is involved in various fields such as physics, chemistry, biology, space earth science, life science, environmental science, and agriculture. In our laboratory, we promote cross-disciplinary research in collaboration with researchers in various fields.

In addition, we became a member of the Department of Chemistry in October 2023. We are conducting interdisciplinary research to evaluate and utilize the original mass spectrometry technology developed in our laboratory. In collaboration with researchers in other fields and companies, we conduct a wide range of research on molecular information measurement, as well as applied research aimed at environmental measurement and medical diagnosis. Mass spectrometry imaging research to visualize chemical components of biological tissues and cells aims to elucidate the mechanisms of diseases and to apply it to diagnosis.

Our laboratory is unique in that students from both physics and chemistry majors belong to the same laboratory. We hope that students with different backgrounds can stimulate each other and promote unique research.

We welcome laboratory tours at any time, so please contact us for more information.
