    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.

    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).

    Nóta The major advantage MS has is the use of tandem MS-MS. The detector may be programmed to select certain ions to fragment. The process is essentially a selection technique, but is in fact more complex. The measured quantity is the sum of molecule fragments chosen by the operator. As long as there are no interferences or ion suppression, the LC separation can be quite quick. It is common now to have analysis times of 1 minute or less by MS-MS detection, compared to over 10 mins with UV detection

    Nóta Inzwischen sind verschiedene Verfahren der Massenspektrometrie entwickelt worden, die sich vor allem durch die Art der Ionisierung des jeweiligen Analyten und durch die nachfolgende Ionen-Auftrennung unterscheiden. Eines dieser Verfahren ist die sogenannte MALDI-TOF MS. Das Kürzel steht für Matrix-Assisted Laser Desorption/Ionisation Time of Flight Mass Spectrometry, eine Technik zur massenspektrometrischen Auftrennung von Makromolekülen, welche 1985 von F. Hillenkamp und M. Karas entwickelt wurde. Das Besondere hierbei ist die schonende Ionisierung, bei der die Analytmoleküle nicht zerstört werden. Dadurch ermöglicht diese Methode erstmals auch die Analyse von nicht-flüchtigen Biomolekülen größerer Molekülmasse (über 20–30 kDa) wie Proteinen und Peptiden, sowie von komplexen Analytmischungen. Daher ist sie zu einer der wichtigsten Methoden in der Proteomanalytik geworden.
