Latest Patents
One of his latest inventions is an ion analyzer. This device includes a first member fixed to an ion outflow port, which is equipped with a fixing pin on one side and a pin hole on the other side, effectively sandwiching the ion outflow port. The second member is designed to be fixed to the first member and features an ion flow controller that regulates the movement of ions flowing out from the ion outflow port. This second member also has a first concave part that engages with the fixing pin from a direction perpendicular to the axis of the fixing pin, and a second concave part that engages with an insertion pin to be inserted into the pin hole from a different direction. Additionally, a pin member is included, which has an insertion pin inserted into the pin hole and a head part that sandwiches and fixes the second concave part with the first member.
Another notable invention by Toji is an ionizer and mass spectrometer. This device comprises an ionization chamber and a sample nozzle that allows a liquid sample to flow into the ionization chamber. It also features an assist gas passage that supplies an assist gas to promote the desolvation of the liquid sample. A heater is located inside the assist gas passage, along with a heat transfer member that is in contact with the heater. This heat transfer member can be positioned inside the heater, which includes a spirally wound heater wire, and between the heater and the inner wall surface of the assist gas passage.
