Summary
[edit]DescriptionHeadspace-Technik in der Gaschromaotgraphie.png |
Deutsch: Eine komplexe Probe (z.B. Blut, Honig, Textilstück) wird in ein gasdichtes Gefäß gegeben und nach thermischer Einstellung der Phasengleichgewichte mithilfe einer Nadel durch den Autosampler eine Gasportion entnommen und der Säule zur Analyse/Trennung zugeführt. Vorteile: 1. Probebestandeile können nicht die Säule harnäckig verunreinigen/verstopfen. 2. Auf eine komplexe Probenaufarbeitung (z.B. in Lösung bringen) kann so häufig verzichtet werden. |
