摘要： Methods and apparatus for operating a mass spectrometer are described. In various aspects, ions of a mass range of interest may be mass-selectively ejected from an accumulation ion trap into a multi-ion trap structure. Each ion trap of the multi-ion trap structure may be configured to confine ions within a portion of the mass range of interest. The ions may be simultaneously scanned from the ion traps of the multi-ion trap structure for concurrent detection at a detector component.

摘要： This invention provides a method of mounting cylindrical electrodes in the geometry of a miniature electrostatic quadrupole, which can act as a quadrupole mass filter or a quadrupole ion guide, or be used in a linear quadrupole ion trap. The electrodes are mounted in pairs on microfabricated supports, which are formed from conducting parts on an insulating substrate. The supports include a suspended flexure system to relieve strains caused by mismatch between the thermal expansion coefficients of the electrodes and the substrate. A complete quadrupole is constructed from two such supports, which are spaced apart by further conducting spacers.

摘要： A mass spectrometer includes a radio frequency ion trap and a controller. The controller is configured to cause an ion population to be injected into the radio frequency ion trap and supply an isolation waveform to the radio frequency ion trap. The isolation waveform has at least one notch at a target mass-to-charge ratio and a frequency profile determined to eject unwanted ions at a plurality of frequencies in a substantially similar amount of time.

摘要： A mass spectrometer is disclosed comprising a segmented quadrupole rod set ion trap for trapping ions in axial DC potential wells wherein a potential field is created at the exit of the ion trap which decreases with increasing radius in one radial direction. Ions within the ion trap are mass selectively excited in a radial direction. Ions which have been excited in the radial direction experience a potential field which no longer confines the ions axially within the ion trap but which instead acts to extract the ions and hence causes the ions to be ejected axially from the ion trap.

摘要： Provided are three-dimensional (3D) nanodevices including 3D nanostructures. The 3D nanodevice includes at least one nanostructure, each nanostructure including an oscillation portion floating over a substrate and support portions for supporting both lengthwise end portions of the oscillation portion, supports disposed on the substrate to support the support portions of each of the nanostructures, at least one controller disposed at an upper portion of the substrate, a lower portion of the substrate, or both the upper and lower portions of the substrate to control each of the nanostructures, and a sensing unit disposed on each of the oscillation portions to sense an externally supplied adsorption material. Thus, unlike in a typical planar device, generation of impurities between a nanodevice and a substrate can be reduced, and mechanical vibration can be caused. In particular, since 3D nanostructures have mechanical and electrical characteristics, 3D nanodevices including new 3D nanostructures can be provided using nano-electro-mechanical systems (NEMS). Also, a single electron device, a spin device, or a single electron transistor (SET)-field effect transistor (FET) hybrid device can be formed using a simple process unlike in planar devices.
