Ionization detector
WebFlame Ionization Detector. The flame ionization detector (FID) is the most widely used detector for gas chromatography because of its reliability, versatility, and ease of use. It responds to virtually any organic compound while generating little or no signal for common carrier gases. The auto-ranging FID used on Agilent Intuvo 9000, 8890, 8860 ... WebThe ionizing effect of radiation on a gas is extensively used for the detection of radiation such as alpha, beta, gamma, and X-rays. The original ionization event in these instruments results in the formation of an "ion pair"; a positive ion and a free electron, by ion impact by the radiation on the gas molecules.

WebThe present invention relates to an apparatus for detection of ionizing radiation, wherein the incident radiation ionizes a substance, and the electrons released as a result thereof are accelerated in a dual parallel plate electrode arrangement (17, 19, 21). These electrons will interact with a scintillating substance to emit light, which is detected by a position … WebFlame and Photo Ionization Detectors, Portable Portable Flame Ionization Detectors (FIDs) are used by first responders to detect the presence of organic compounds, including hydrocarbons and volatile organic compounds (VOCs). These substances may be toxic or form flammable or explosive mixtures with air, so it is important for
In deze detector brandt een waterstofvlammetje dat tussen twee elektroden geplaatst is. De componenten die de kolom verlaten worden hierdoorheen geleid. Ze verbranden dan, waarbij ionen gevormd worden. Deze ionen zorgen ervoor dat er een klein elektrische stroompje tussen de elektroden gaat … Meer weergeven Een vlamionisatiedetector (Engelse afkorting: FID, Flame Ionization Detector) is een detector die wordt gebruikt in de gaschromatografie.
