Latest Patents

Ueda holds one patent titled "Quadrupole mass filter and quadrupole mass spectrometer." This invention features four main rod electrodes arranged in a rotationally symmetric manner around an ion optical axis. The design includes four pre-rod electrodes that create a unique rotational asymmetry. This innovative approach results in an elliptical acceptance shape on the x-y plane for ions, which allows for a gradual flattening of this shape as ions pass along the optical axis. Such adjustments dramatically reduce mismatches between the incoming ion emittance and the acceptance on the receiving side, ultimately minimizing ion loss during introduction.
