  • Field asymmetric ion mobility spectrometry filter
    Patent number: 10002750
    Abstract: Ion filter for FAIMS fabricated using the LIGA technique. The ion filter is manufactured using a metal layer to form the ion channels and an insulating support layer to hold the structure rigidly together after separation of the metal layer into two electrodes.

  • Field asymmetric ion mobility spectrometry system
    Patent number: 9976985
    Abstract: An apparatus, system and method for detecting, identifying, classifying and/or quantifying chemical species in a gas flow using a micro-fabricated ion filter coupled to a system adapted to apply drive signals to the ion filter. Coupled to the ion filter is a system adapted to measure the output of the ion filter, which in turn is coupled to a system adapted to extract numerical parameters from the measured output of the ion filter to facilitate chemical detection, identification, classification and/or quantification of the gas flow.

  • Sensor apparatus and method for use with gas ionization systems
    Patent number: 9953818
    Abstract: An ion mobility gas detector apparatus including a detector core, an inlet gas path, an exhaust gas path, a source of diluent gas, and at least one or more sensors for measuring temperature, pressure and humidity of gas streams. Further included is a mixing mechanism adapted to mix at least first and second gas streams in response to one or more sensor measurements. A controller is provided for applying drive signals to the detector core.
