Abstract: A mass spectrometer that employs ion velocity mapping. The mass spectrometer includes velocity mapping ion optics that focus the ions based on their velocity. The focused ions are then directed into a deflection region between two deflection plates. A pulse is applied to the deflection plates that deflect the ions in a transverse direction also according to their mass. The pulse is turned on before the first ion in an ion packet reaches the deflection region, and is turned off before the first ion exits the deflection region. The focused and deflected ions are then reflected by a reflecting device that directs the ions along separate paths to a detector. The detector provides an image of the ion paths, where the location of a spot on the image represents ions of a certain mass and the size of the spot indicates the various velocities of the ions of that mass.

Abstract: An improved sample introduction probe is disclosed for the production of ions from liquid sample solutions in an electrospray ion source. Nebulization of a liquid sample emerging from the end of an inner flow tube is pneumatically assisted by gas flowing from the end of an outer gas flow tube essentially coaxial with the inner sample flow tube. The disclosed probe provides for adjustment of the relative axial positions of the ends of the liquid and gas flow tubes without degrading the precise concentricity between the inner and outer tubes. Additionally, the terminal portion of the outer gas flow tube may be fabricated either from a conductive or dielectric material, thereby allowing the pneumatic nebulization and electrospray processes to be optimized separately and independently. Hence, the disclosed invention provides a pneumatically-assisted electrospray probe with improved mechanical and operational stability, reliability, reproducibility, and ease of use compared to prior art probes.

Abstract: The present invention realizes a nanotube probe with high durability that can be manufactured in short time with less impurities adhered to the holder sustaining the nanotube. The nanotube probe according to this invention is constructed by fastening a nanotube 8 on the protruded portion 4 of a cantilever by way of at least two partial coating films 12a and 12b. One or more additional partial coating films may be formed in the intermediate area between these two partial coating films. Each partial coating film is formed by irradiating electron beam 10 on the position where the nanotube 8 is in contact with the protruded portion 4 of the cantilever. The partial coating films are separated not to overlap each other. By minimizing the size of partial coating film as well as by narrowing down the beam diameter, coating time may be further shortened. With the beam diameter narrowed down, excessive deposit of impurities can be put under control.
