  • Quadrupol ion trap mass spectrometer with cryogenic particle detector
    Patent number: 6710334
    Abstract: This invention relates to a quadrupol ion trap mass spectrometer with improved sensitivity for massive molecules by using cryogenic particle detectors as molecule detectors. Cryogenic particle detectors have a mass independent detection efficiency and do not show a decrease of detection efficiency for increasing molecule mass as compared to ionizing detectors which are used in common quadrupol ion trap mass spectrometers.

  • Micromechanically produced nozzle for producing reproducible droplets
    Patent number: 6523762
    Abstract: The invention relates to a micromechanically produced nozzle for producing reproducibly small drops which consist of a liquid container delimited by a silicon structure and a pyrex structure. The silicon structure is a silicon wafer consisting of a silicon oxide layer (SiO2) and a silicon nitride layer (SI3N4). The wafer has a nozzle of silicon oxide (SiO3), which forms a nozzle opening of a liquid container. The liquid is fed into the liquid container through a channel formed in the pyrex structure. A disk made of a piezoelectric material exerts a pressure on the liquid in the container, which passes through the nozzle in the form of a drop.

  • Mass spectrometer for macromolecules with cryogenic particle detectors
    Patent number: 5640010
    Abstract: A mass spectrometer with phonon sensitive cryogenic particle detector determines the masses of macromolecules, proteins, large peptides, long DNA-fragments and polymers. The kinetic energy of the electrostatically accelerated charged macromolecule is absorbed in the cryogenic particle detector thereby exciting phonons which are detected by phonon sensors. The macromolecules are detected in the single particle counting mode with a sensitivity independent of their respective masses. The mass spectrometer contains a single-channel cryogenic particle detector providing high sensitivity. The mass spectrometer contains a spatially resolving multi-channel cryogenic detector array providing both high sensitivity and high throughput. The mass spectrometer consists of a vacuum vessel in which is a magnet, a mass separator, a feed through and a phonon sensitive cryogenic detector array. The cryogenic detector array consists of an absorber and a specified number of phonon sensors.
