摘要： An ionization gas sensor includes a first electrode and a second electrode, such as cathode and anode electrodes. The second electrode is a carbon nanotube film having a carbon nanotube density such that the film behaves as a conducting sheet electrode. The sensor also includes a voltage source electrically connected to the first and to the second electrodes. The voltage source is adapted to generate an electric field near tips of carbon nanotubes in the carbon nanotube film which induces electrical breakdown of an analyte gas, which leads to a self-sustaining inter-electrode arc discharge

摘要： A method and system for measuring the flow rate of a liquid or gas within a flow channel utilizing a centrally located excitation source and a plurality of sensor means. Said excitation means is comprised of a heating element coupled with an alternating current generator. Of the plurality of sensor means, at least one of said sensors is located in a position upstream of the excitation source location, and additionally a second of said plurality of sensors is located in a position downstream of the excitation source. Instantaneous fluid flow rate is calculated utilizing a high gain differential amplifier electrically coupled to said sensors, wherein the convectively induced inductive gradient of the flowing fluid is compared to the symmetrical zero flow induction gradient. Following such a comparison, a voltage signal proportional to the flow of fluid within the channel is derived.

摘要： An ion pump having conductive electrodes on both sides of an insulator which may form a number of channels. These electrodes may provide electrical discharges which have a corona or cold cathode emission for ionization. The electrodes and the insulator may be layers having openings that form the channels. The openings in one electrode layer may have a sharp-like configuration and the openings in the other electrode layer may have a non-sharp-like configuration. Ions may be predominately in-situ generated proximate to the sharp-like openings and have the polarity of these openings. These ions may induce a fluid flow through the channels of neutral molecules as a result of a force and viscous drag of the ions. The sharp-like openings may have nanotube whiskers or a thin film structure for facilitating an electrical discharge.

摘要： An ionization detector includes a unique combination of elements including a non-radioactive glow discharge source, a gas flow area designed to promote mixing of sample gas with a reagent gas, a GC column interface which directs air leaks away from the sample area, and a signal electrode designed to discriminate against ion collection. This embodiment includes a body defining a detector cavity and a sample flow area. A plurality of electrodes are disposed within the body including a glow discharge source comprising a first and second discharge electrode located near one end of the body, a guard electrode located longitudinally intermediate to the discharge electrode and the sample flow area, and a signal electrode disposed within a signal electrode cavity located near an end opposite to the guard electrode. A column interface depends from the body, in communication with the sample flow area. The column interface includes a reagent inlet and a purge outlet which extend laterally from a longitudinal portion of the column interface. A column from a GC extends through the longitudinal portion and is partially disposed within the sample flow area.
