Flame detector — A flame detector is a detector that uses optical sensors to detect flames.TypesUltravioletUltraviolet (UV) detectors work with wavelengths shorter than 300 nm. These detectors detect fires and explosions within 3–4 milliseconds due to the UV… … Wikipedia
Flame ionization detector — A flame ionization detector (FID) is a type of gas detector used in gas chromatography. The first flame ionization detector was developed in 1957 by scientists working for the CSIRO in Melbourne, Australia.… … Wikipedia
Flame Programmer — A flame programmer is an electrical, electro mechanical, or electronic device used to program the safe lighting of fuel burning equipment, as well as the safe shut down of the flame when it is not needed.These programmers are made with different… … Wikipedia
flame ionization detector — (FID) A nearly universal gas chromatographic detector. It responds to almost all organic compound. An FID does not respond to nitrogen, hydrogen, helium, oxygen, carbon monoxide or water. This detector ionizes compounds as they reach the end… … Forensic science glossary
Heat detector — A heat detector is a device that responds to changes in ambient temperature. Typically, if the ambient temperature rises above a predetermined threshold an alarm signal is triggered. In the case of sprinkler systems, water will be released to… … Wikipedia
Chromatography detector — A chromatography detector is a device used in gas chromatography (GC) or liquid chromatography (LC) to visualize components of the mixture being eluted off the chromatography column. There are two general types of detectors: destructive and non… … Wikipedia
Gas chromatography ion detector — Many GC detectors are ion detectors with varying methods of ionizing the components eluting from the GC s column.Principle of OperationAn ion detector is analogous to a capacitor or vacuum tube. It can be envisioned as two metal grids separated… … Wikipedia
Thermal conductivity detector — The thermal conductivity detector (TCD) is a bulk property detector and a chemical specific detector commonly used in gas liquid chromatography. [Grob, Robert L. Ed.; Modern Practice of Gas Chromatography , John Wiley Sons, C1977, pg. 228, ] This … Wikipedia
Gas detector — A gas detector is a device which detects the presence of various gases within an area, usually as part of a system to warn about gases which might be harmful to humans or animals. Gas detectors can be used to detect combustible, toxic, and oxygen … Wikipedia
thermal conductivity detector — A type of gas chromatographic detector which is sensitive to the change in the ability of the gases emerging from the column to conduct heat. A thermal conductivity (TC) detector is not as sensitive as a flame ionization detector, but it is… … Forensic science glossary
photoionization detector — (PID) A type of detector used in chromatography which employs ultraviolet radiation rather than a flame to ionize compounds as they pass through a detector. Photoionization detectors are particularly sensitive to aromatic compounds … Forensic science glossary
