Latest Patents
Kohnosuke Ohishi holds a patent for a "Light source excited by high frequency for Zeeman effect atomic." This invention provides a light source that can be utilized in atomic absorption analysis by employing the Zeeman effect. The design involves applying an external magnetic field to a hollow cathode, which causes the Zeeman-splitting of an emission line from the cathode material. The hollow cathode is constructed from a ferromagnetic metal, which is the element of interest for analysis, and a metal that reduces the magnetic shield of the externally applied magnetic field. This design ensures that the external magnetic field effectively influences the hollow portion of the cathode, achieving the desired Zeeman-splitting. The emission line is generated by excitation from a high-frequency power supply connected to both the cathode and anode of the light source.
