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.

Corona ionization apparatus and method

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 filter

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.

Field asymmetric ion mobility spectrometry system

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.

Sensor apparatus and method for use with gas ionization systems

Corona ionization device and method

A fluid pump comprising one or more actuators, two end walls, a side wall; a cavity which, in use, contains fluid, the cavity having a substantially cylindrical shape bounded by the end walls and the side walls, at least two apertures through the cavity walls, at least one of which is a valved aperture, wherein the cavity radius, a, and height, h, satisfy the following inequalities: a/h is greater than 1.2; and h/a is greater than 4&#xd7;10m; and wherein, in use, the actuator causes oscillatory motion of one or both end walls in a direction perpendicular to the plane of the end walls; whereby, in use, the axial oscillations of the end walls drive radial oscillations of fluid pressure in the cavity.

Acoustic pump utilizing radial pressure oscillations

A fluid consuming battery () is provided with a fluid regulating system () for regulating fluid entry into the battery. The battery () includes a fluid consuming cell () having a cell housing with fluid entry ports for the passage of a fluid into the cell housing. A first fluid consuming electrode and a second electrode are disposed within the cell housing. The fluid regulating system () includes a valve having a moving plate () disposed adjacent to a fixed plate (). The moving plate and fixed plate both have fluid entry ports () that align in an open valve position and are misaligned in a closed valve position. The fluid regulating system () also includes an actuator that may include one or more shape memory alloy (SMA) components () for moving the moving plate () relative to the fixed plate () to open and close the valve.
