  • Patent number: 9607819
    Abstract: A non-radioactive plasma ion source device includes at least four planar electrodes that define at least three chambers, including a discharger chamber and at least two additional chambers aligned along a major longitudinal axis of the housing. A discharger ionizes at least one of a transport gas and a discharge gas to form ions in the discharger chamber that are directed by a homogeneous electric field generated by the planar electrodes toward an analyte gas outlet. Ionized species of at least one of the transport gas and the discharge gas that are not entrained by a counterflow gas stream are discharged from the discharger chamber to form a stream of ionized particles that ionize a sample gas and thereby form a stream of ionized analyte particles of the same polarity. The ionized analyte particles are entrained with the stream of ionized particles and pass through an analyte gas outlet to an analyzer.

  • Patent number: 8410432
    Abstract: A ion mobility-based analyzer system including a first ion mobility-based filter for passing selected ions through a time-varying field where the time-varying field being compensated by an adjustable compensation setting. The analyzer also includes a second ion mobility-based filter for receiving a first portion of ions from the first ion mobility-based filter. The second ion mobility-based filter includes a voltage gradient for separating ions of the first portion of ions where the ions have associated retention times based on their times of flight through the voltage gradient. The second ion mobility-based filter includes a detector for detecting the ions at their retention times. The analyzer system further includes a display that displays the detected ions in a plot relating the retention times of the ions in the second ion mobility-based filter with compensation settings of the first ion mobility-based filter.
