Latest Patents

Yamauchi's latest patents include an advanced ion analyzer. This device features an ionization chamber, an ionization unit configured to generate ions from a sample, and an analysis chamber separated from the ionization chamber by a partition wall. The ion transport unit is designed to transport the generated ions, while the ion trapping unit captures these ions for detection. Additionally, a single evacuation mechanism is connected to the analysis chamber, allowing it to reach a pressure of 10Pa or less.

Another notable patent is a mass spectrometry method and mass spectrometer. This invention involves acquiring first product ion spectrum data by dissociating a precursor ion through collisions with inert gas molecules. The product ions are then detected after being separated according to their mass-to-charge ratio. A second set of product ion spectrum data is obtained by reacting the precursor ion with hydrogen radicals. This innovative approach allows for the extraction of a set of product ions with a predetermined mass difference.
