  2. Gas chromatography - Wikipedia

    en.wikipedia.org/wiki/Gas_chromatography

    Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [ 1 ]

  3. Gas chromatography–mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Gas_chromatography–mass...

    GC–MS is used for the analysis of unknown organic compound mixtures. One critical use of this technology is the use of GC–MS to determine the composition of bio-oils processed from raw biomass. [29] GC–MS is also utilized in the identification of continuous phase component in a smart material, magnetorheological (MR) fluid. [30]

  4. Electron capture detector - Wikipedia

    en.wikipedia.org/wiki/Electron_capture_detector

    Electron capture detector developed by James Lovelock in the Science Museum, London Electron capture detector, Science History Institute. The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph.

  5. Chromatography software - Wikipedia

    en.wikipedia.org/wiki/Chromatography_software

    The integrated areas are compared to a calibration curve, created using standards' concentrations to calculate the concentration of each component in the unknown sample. Data Interpretation : The software analyzes the integrated data to draw conclusions about the composition, concentration, and purity of the sample.

  6. Pyrolysis GC/MS chromatogram of mahogany wood analyzed with OpenChrom. Pyrolysis–gas chromatography–mass spectrometry is a method of chemical analysis in which the sample is heated to decomposition to produce smaller molecules that are separated by gas chromatography and detected using mass spectrometry.

  7. Headspace gas chromatography for dissolved gas measurement

    en.wikipedia.org/wiki/Headspace_Gas...

    One of the most widely used methods for headspace analysis is described by the United States Environmental Protection Agency (USEPA). Originally developed by the R.S. Kerr USEPA Laboratory in Ada, Oklahoma as a "high quality, defendable, and documented way to measure" methane, ethane, and ethene, [7] [8] RSKSOP-175 is a standard operating procedure (SOP) and an unofficial method employed by ...
