Patents by Inventor Katrin Fuhrer

Katrin Fuhrer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20050127289
    Abstract: Time-of-flight mass spectrometer instruments for monitoring fast processes using an interleaved timing scheme and a position sensitive detector are described. The combination of both methods is also described.
    Type: Application
    Filed: October 18, 2004
    Publication date: June 16, 2005
    Inventors: Katrin Fuhrer, Marc Gonin, Kent Gillig, Thomas Egan, Michael McCully, J. Schultz
  • Patent number: 6897437
    Abstract: The present invention relates to an improved ion mobility spectrometer and method for the analysis of chemical samples. The improvements are realized in the optimization of resolution and sensitivity. Increases in sensitivity are realized by preserving a narrow spatial distribution of migrating ions through the use of periodic/hyperbolic field focusing. Additionally, novel combinations and configurations of components are used to simultaneously maintain a well defined ion packet and preserve sample throughput to the detector.

  • Publication number: 20050006577
    Abstract: Time-of-flight mass spectrometer instruments are disclosed for monitoring fast processes with large dynamic range using a multi-threshold TDC data acquisition method or a threshold ADC data acquisition method. Embodiments using a combination of both methods are also disclosed.

  • Publication number: 20040217275
    Abstract: A detection scheme for time-of-flight mass spectrometers is described that extends the dynamic range of spectrometers that use counting techniques while avoiding the problems of crosstalk. It is well known that a multiple anode detector capable of detecting different fractions of the incoming particles may be used to increase the dynamic range of a TOFMS system. However, crosstalk between the anodes limits the amount by which the dynamic range may be increased. The present invention overcomes limitations imposed by crosstalk by using either a secondary amplification stage or by using different primary amplification stages.
