摘要： 842,897. Discharge tubes. GENERAL ELECTRIC CO. Dec. 20, 1956 [Dec. 20, 1955], No. 38875/56. Class 39(1). In a vapour detector in which the atmosphere containing the substance to be detected is passed between a negative collector electrode and a heated positive emitter electrode supported on a ceramic core, and the positive ion current is measured, positive ion emitting material containing an alkali metal glass is interposed between the core and the emitter electrode to supply positive ions when detecting substances such as halogen compounds which have an ionization potential higher than the work function of the emitter electrode surface. The detector shown comprises a cylindrical core 12 of ceramic material preferably having a high alumina content supported on two rods 16 and 17 which are retained in openings 10b and 10c in the end wall of a ceramic housing 10, which end wall also has openings 10d and 10e through which vapour may enter or be discharged. A heater coil 13, e.g. of an alloy of 90% platinum and 10% rhodium, is wound on the core 12 with one end 18 wrapped around the rod 16 and the other end 20 wrapped around the rod 17, and is buried in a coating 15 of positive ion emitting material containing an alkali metal glass known as B-eucryptite (Li2O Al2O3. 2SiO2). A cylindrical emitter electrode 14, preferably of platinum, surrounds and is in contact with the coating 15 and is connected to the rod 16 by a strap 23. A cylindrical collector electrode 24, preferably of platinum, is maintained with its upper flared end 24a engaging a shoulder 10g in the housing 10 by a ceramic washer 25 having a plurality of sloping fingers 25a which engage the lower end of the electrode. The washer 25 is held in engagement with a shoulder 10h by bent portions 16a and 17a of the rods 16 and 17 which are secured to bolts 21 and 22 mounted in a flange 10a at the open end of the housing 10 and forming terminals for the heater coil 13. A conductor 26 having one or two turns 26a wrapped around the electrode 24 is spaced from the electrode 24 and is bent at the end and secured to a terminal bolt 27. The construction is such that the heat loss from the emitter and collector electrodes is kept to a minimum. The emitter electrode attains a temperature between 700 and 925‹C.

摘要： A sensor for detecting properties of a gas, gas mixture, or a gas or gas mixture containing particles, all collectively referred to as a “gas”. A flow tube contains a pair of electrodes arranged such that at least a portion of the gas flows between the electrodes. A controller applies voltage to the electrodes and measures response data from the electrodes representing the voltage-current relationship and voltage breakdown between the electrodes while the gas is between the electrodes. Based on the response data, the controller determine a concentration of the gas or a concentration of particles within the gas.

摘要： The invention relates to an ionization vacuum measuring cell (10) comprising an evacuable housing (12) with a measurement connection for a vacuum to be measured at an end portion; a measurement chamber (14) in the housing (12), said measurement chamber being fluidically connected to the measurement connection, wherein the measurement chamber (14) is designed as a replaceable component; and a first and a second electrode (16, 18) in the measurement chamber (14), said electrodes being substantially coaxial to an axis and being arranged at a distance from each other. The measuring cell further comprises an electrically insulating and vacuum-tight feedthrough (20) for an electric supply to the second electrode (18) and a magnetization assembly which is designed to generate a magnetic field in the ionization chamber. According to the invention, the measurement chamber (14), in particular at least one of the electrodes (16, 18), comprises a magnetic material.

摘要： A dielectric barrier discharge ionization detector capable of achieving a high signal-to-noise ratio is provided. The detector includes: a discharging section for generating plasma from argon-containing gas by electric discharge; and a charge-collecting section for ionizing a component in a sample gas by an effect of the plasma and for detecting ion current formed by the ionized component. The discharging section includes a cylindrical dielectric tube having a high-voltage electrode connected to AC power source as well as upstream-side and downstream-side ground electrodes and formed on its outer circumferential wall. A semiconductor film is formed on the inner circumferential surface of the tube. The upstream-side and downstream-side ground electrodes are respectively made longer than the initiation distances for a creeping discharge between the high-voltage electrode and a tube-line tip member as well as between the high-voltage electrode and the charge-collecting section.
