    gas chromatography with an electron capture detector | Gas Chromatography / Electron Capture Detection
    en
    Definition gas chromatography method associated with a detector which uses a radioactive beta emitter (electrons) to ionise some of the carrier gas and produce a current between a biased pair of electrodes, so that when organic molecules that contain electronegative functional groups, such as halogens, phosphorous, and nitro groups pass by the detector, they capture some of the electrons and reduce the current measured between the electrodes Reference COM-Terminology Coordination, based on:Shimadzu GC-8A with ECD Detector: Gas Chromatography.

    Comment 'Retention time' is one of the most important chromatographic features for analytical chemists since it is the key parameter to separate, identify and quantify compounds of interest from complex mixtures. Although detectors with higher-dimensional signals ease the identification of many components, there are demanding requirements on the retention time, particularly when high-throughput methods are considered. In addition to this, gas chromatographic elution shows significant run-to-run variations due to fluctuations in temperature and pressure, column degradation or matrix effects. In this sense, different approaches have been developed to minimise those variations: the introduction of electronic pneumatic control (EPC) systems, which allow a very efficient control of the flow of the carrier gas, the use of peak alignment algorithms to treat the chromatograms, or the use of retention-time locking (RTL).
