atmospheric pressure discharge
1Atmospheric pressure discharge — An atmospheric pressure discharge is an electrical discharge in air at atmospheric pressure.An electrical discharge is a plasma, which is an ionized gas. Plasmas are sustained if there is a continuous source of energy to maintain the required… …
2Atmospheric Pressure Chemical Ionization — (chemische Ionisation bei Atmosphärendruck, APCI) ist ein Ionisierungsverfahren, das in Massenspektrometern verwendet wird. Es ist eine Form der chemischen Ionisierung bei atmosphärischen Druck. Eine Lösung des Analyten wird durch eine Kapillare… …
3Atmospheric pressure chemical ionization — Infobox chemical analysis name = Atmospheric pressure chemical ionization caption =Atmospheric pressure chemical ionization interface acronym = APCI classification =Mass spectrometry analytes = Organic molecules Biomolecules related = Chemical… …
4Low pressure discharge — Low pressure discharges are those that have gas pressures from a few millitorr to a little less than atmospheric. They have the benefit of less power requirement of sustenance of the discharge as volume recombination rates are lower.It is easier… …
5Atmospheric electricity — is the regular diurnal variations of the Earth s atmospheric electromagnetic network (or, more broadly, any planet s electrical system in its layer of gases). The Earth’s surface, the ionosphere, and the atmosphere is known as the global… …
6Pressure cooking — is a method of cooking in a sealed vessel that does not permit air or liquids to escape below a preset pressure. Because the boiling point of water increases as the pressure increases, the pressure built up inside the cooker allows the liquid in… …
7Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
8pressure — [1] The force due to the weight of a substance exerted over the area the substance occupies. In metric measure, it is the force acting on each square metre. To calculate pressure, divide the force (in newtons) by the area (in square metres). It… …
9Gas-discharge lamp — See also: Gas filled tube Germicidal lamps are simple low pressure mercury vapor discharges in a fused quartz envelope. Gas discharge lamps are a family of artificial light sources that generate light by sending an electrical discharge through an …
10Dielectric barrier discharge — (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge[1] or partial discharge,[2] it was first reported… …
