    Sulfur monoxide is an inorganic compound with ... Benner and Stedman developed a chemiluminescence detector for sulfur via the reaction between sulfur monoxide ...

  3. Chemiluminescence - Wikipedia

    en.wikipedia.org/wiki/Chemiluminescence

    A typical example is NO determination with detection limits down to 1 ppb. Highly specialised chemiluminescence detectors have been used recently to determine concentrations as well as fluxes of NO x with detection limits as low as 5 ppt.

  4. Photoionization detector - Wikipedia

    en.wikipedia.org/wiki/Photoionization_detector

    In a photoionization detector, high-energy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged ions. [2] As compounds enter the detector they are bombarded by high-energy UV photons and are ionized when they absorb the UV light, resulting in ejection of electrons and the formation of positively charged ions.

  5. Ultrasound-enhanced chemiluminescence - Wikipedia

    They are commonly used in biomedical detection and analysis as luminophores or substrates in chemiluminescence assays. Acridinium does not require a catalyst to produce chemiluminescence. Hydrogen peroxide (H 2 O 2) and a strong base are sufficient to cause acridinium esters to produce chemiluminescence. [1]

  6. Flow injection analysis - Wikipedia

    en.wikipedia.org/wiki/Flow_injection_analysis

    FIA is an automated method of chemical analysis in which a sample is injected into a flowing carrier solution that mixes with reagents before reaching a detector. Over past 30 years, FIA techniques developed into a wide array of applications using spectrophotometry , fluorescence spectroscopy , atomic absorption spectroscopy , mass spectrometry ...

  7. Electron capture detector - Wikipedia

    en.wikipedia.org/wiki/Electron_capture_detector

    The detection limit for electron capture detectors is 5 femtograms per second (fg/s) and the detector commonly exhibits a 10,000-fold linear range. [ citation needed ] This made it possible to detect halogenated compounds such as pesticides and CFCs , even at levels of only one part per trillion ( ppt ), thus revolutionizing our understanding ...

  8. Air pollution measurement - Wikipedia

    en.wikipedia.org/wiki/Air_pollution_measurement

    Sulfur dioxide (SO 2) is measured by fluorescence spectroscopy. This involves firing ultraviolet light at a sample of the air and measuring the fluorescence produced. [45] Absorption spectrophotometers are also used for measuring SO 2. Flame photometric analyzers are used for measuring other sulphur compounds in the air. [46]

  9. Chromatography detector - Wikipedia

    en.wikipedia.org/wiki/Chromatography_detector

    A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.
