    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.

    Abstract: An ion filter (10) for use in ion mobility spectrometry is described, together with a method for manufacturing the filter. The filter (10) is manufactured by removing portions from a monolithic structure to form a pair of electrodes which remain mechanically connected. The connecting portion (22) provides sufficient electrical impedance between the electrodes to effectively electrically separate the electrodes. The connecting portion may be doped or chemically modified to obtain a desired impedance, or this may be obtained through appropriate selection of physical dimensions.

    Abstract: A corona discharge ionizer device which emits ions generated by corona discharge to a gas flow to be ionized includes a discharge electrode having a pin configured tip portion. A second grid electrode positioned at a spaced distance from the discharge electrode is provided. The grid electrode is preferably formed from a sheet configured material which has at least one hole formed therein adapted and configured to permit the gas flow to pass therethrough. A power supply is coupled to the discharge electrode and grid electrode configured cause ion emission from the discharge electrode. The power supply is preferably an alternating current power supply configured to produce an alternating electric field region in close proximity to the tip portion of the discharge electrode sufficient to cause avalanche breakdown in the gas flowing in close proximity to the tip portion of the discharge electrode.
