WebGel permeation chromatography (GPC) is a type of size exclusion chromatography (SEC). It is mainly used to measure the molecular weight of polymer compounds. The molecular weight distribution shows how much molecular weight contains in a sample, and it is widely used for quality control to know the difference in the properties of polymer compounds. WebPermeation ist die Durchdringung von Gas oder Dampf durch eine Barriere, wie etwa die einer Folie oder auch einer Verpackung von Lebensmittel und Medizinprodukte oder sogar flexible elektronische Displays. Aufgrund der Partialdruckdifferenz durchdringt dabei das Gas oder der Dampf die Barriere, die meistens aus einem Feststoff ist.
