    Nóta "Gas chromatography is always carried out in a column. It is a common type of chromatography used in organic chemistry for separating and analysing compounds that can be vaporised without decompositionIn gas chromatography the distinction between gas-liquid and gas-solid may be obscure because liquids are used to modify solid stationary phases, and because the solid supports for liquid stationary phases affect the chromatographic process. For classification by the phases used, the term relating to the predominant effect should be chosen.See also:- gas chromatography/mass spectroscopy (related) [ IATE:1295813 ]- gas chromatographic separation (related) [ IATE:1094399 ]- gas-liquid chromatography (narrower) [ IATE:1479581 ]- gas-solid chromatography (narrower) [ IATE:1717974 ]"

    en
    Nóta "'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)."

    Sainmhíniú Die Gaschromatographie eignet sich zur Bestimmung aller gasförmigen o. unzersetzt verdampfbaren Stoffe, also im wesentlichen von organischen Verbindungen. Eine Probe des zu untersuchenden Stoffgemisches wird in einen Trägergasstrom gebracht und durchströmt eine Trennsäule oder -kapillare mit einer speziellen Füllung bzw. Beschichtung. Stoffabhängige Wechselwirkungen in der Säule bewirken, daß die einzelnen Verbindungen unterschiedlich lange zurückgehalten werden und am Ende der Säule zeitlich getrennt austreten. Zur Detektion der austretenden Komponenten stehen verschiedene Techniken zur Verfügung. Mit einem nachgeschalteten Massenspektrometer lassen sich gleichzeitig Aussagen über Art und Menge der jeweiligen Substanz machen (Identifizierung und Quantifizierung). Dazu werden die austretenden Teilchen ionisiert und die gebildeten Molekülionen, die zum Teil zerfallen, entsprechend ihrem Verhältnis Masse/Ladung in einem Magnetfeld aufgetrennt. Das Muster der auftretenden Fragmente kann einem bestimmten Stoff zugeordnet werden. (Quelle s.o.) Tagairt ---

    Nóta "Gas chromatography ( IATE:1350135 ) separates the components of a mixture and mass spectroscopy ( IATE:1364881 ) characterizes each of the components individually. By combining the two techniques, an analytical chemist can both qualitatively and quantitatively evaluate a solution containing a number of chemicals."

'PREDICTIVE CALCULATION METHODS FOR OPTIMIZATION OF GRADIENT ELUTION USING BINARY AND TERNARY SOLVENT GRADIENTS' (8.2.2024) Journal of Chromatography 485 (1989) 113"
    Nóta There are two types of ternary gradient chromatography defined by Jandera as ternary solvent-strength and combined selectivity-solvent-strength. In the case of the former, the ratio of the concentrations of two organic modifiers is kept constant; whilst the sum of the two concentrations is changed (i.e. the solvent-strength increases). In the latter case the ratio of the two organic modifiers and the sum of their concentrations changes simultaneously during gradient elution.
