Title: Tetsuya Maruo: Innovator in Mass Spectrometry

Introduction

Tetsuya Maruo is a distinguished inventor based in Kodaira, Japan. He is known for his significant contributions to the field of mass spectrometry, particularly through his innovative patent that enhances the sensitivity of mass analysis.

Latest Patents

Maruo holds a patent for a "Laser ionization sputtered neutral mass spectrometer." This invention involves an ion beam that impinges against a solid sample to sputter neutrals. The sputtered neutrals are then ionized by a UV laser beam to obtain photoions. These photoions are guided to a quadrupole mass analyzer through an ion extraction electrode, allowing for the extraction of ions with a desired mass. The extracted ions are directed to an ion detector to derive ion pulses. A counter counts the number of ion pulses through a signal gate that is opened only during the time the photoions reach the ion detector. This method allows for a digital analysis of the mass of the neutrals with a desired mass, enhancing the sensitivity of mass analysis by extending the time period for extracting photoions, thus minimizing noise from secondary ions.
