    Definition 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.) Reference ---

    Comment "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."

    Comment 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.
