Latest Patents

Iwanaga's latest patents include a time-of-flight mass spectrometer and a sample analyzing instrument using first and second plasma torches. The time-of-flight mass spectrometer is designed to cut out a major portion of carrier gas-derived ions ahead of the ion reservoir. It features an electron impact ion source with source magnets that deflect some produced ions away from the center axis of the ion reservoir. Additionally, electrostatic lenses promote the deflection of ions, and a differentially pumped slit cuts off the deflected ions downstream of the ion source. The second patent describes an analytical instrument that utilizes two plasma torches. The first torch vaporizes the sample, while the second excites it for ionization. This innovative approach allows for the analysis of samples without the need for pretreatment, such as dissolving in acid.
