    en.wikipedia.org/wiki/Flame_ionization_detector

    Flame ionization detectors cannot detect inorganic substances and some highly oxygenated or functionalized species like infrared and laser technology can. In some systems, CO and CO 2 can be detected in the FID using a methanizer , which is a bed of Ni catalyst that reduces CO and CO 2 to methane, which can be in turn detected by the FID.

    The nitrogen–phosphorus detector (NPD) is also known as thermionic specific detector (TSD) is a detector commonly used with gas chromatography, in which thermal energy is used to ionize an analyte. [ 1 ] [ 2 ] It is a type of flame thermionic detector (FTD), the other being the alkali flame-ionization detector (AFID also known as AFD).

    Flame ionization detector (FID) -- uses a flame to produce ions; Electron capture detector (ECD) -- uses beta radiation; Photo-ionization detector (PID) -- uses UV light to produce ions; Helium ionization detector (HID) -- uses a radioactive source to produce helium ions, which in turn ionize the components

    Commonly used detectors are the flame ionization detector (FID) and the thermal conductivity detector (TCD). While TCDs are beneficial in that they are non-destructive, its low detection limit for most analytes inhibits widespread use. [1] FIDs are sensitive primarily to hydrocarbons, and are more sensitive to them than TCD. [4]

  6. 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.

    Depending on the required sensitivity, different types of sensors are used (e.g., flame ionization detector, semiconductor, electrochemical, photonic membranes [22]). Detectors usually operate near the lower exposure limit of 25ppm; [ 23 ] however, ammonia detection for industrial safety requires continuous monitoring above the fatal exposure ...
