2. Flame detector - Wikipedia

   en.wikipedia.org/wiki/Flame_detector

   A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection. Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.

4. Flame rectification - Wikipedia

   en.wikipedia.org/wiki/Flame_rectification

   Flame rectification is a phenomenon in which a flame can act as an electrical rectifier. The effect is commonly described as being caused by the greater mobility of electrons relative to that of positive ions within the flame, [ 1 ] and the asymmetric nature of the electrodes used to detect the phenomenon.

5. Graphite furnace atomic absorption - Wikipedia

   The detection limits for the graphite furnace fall in the ppb range for most elements; Interference problems are minimized with the development of improved instrumentation; The graphite furnace can determine most elements measurable by aspiration atomic absorption in a wide variety of matrices.

6. Flame ionization detector - Wikipedia

   en.wikipedia.org/wiki/Flame_ionization_detector

   The design of the flame ionization detector varies from manufacturer to manufacturer, but the principles are the same. Most commonly, the FID is attached to a gas chromatography system. The eluent exits the gas chromatography column (A) and enters the FID detector’s oven (B). The oven is needed to make sure that as soon as the eluent exits ...

7. Flame supervision device - Wikipedia

   en.wikipedia.org/wiki/Flame_supervision_device

   For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished. This is to prevent a dangerous buildup of gas within the appliance, its chimney or the room. [1]
