Oligomers which are always present in polymers evoke attention as potential migrants, from a qualitatively and quantitatively viewpoint. Scope and approach: This article deals with oligomers as potential migrants from plastics food contact materials and reviews their occurrence as well as analytical methods for their identi?cation and quanti?cation. Additionally a section about migration summarizes literature providing oligomer levels in food simulants and foods. Special attention was given to polycondensates since these represent a rapidly expanding polymer ?eld due to increased numbers of (co)-monomers authorized by the EU. Key ?ndings and conclusions: Evaluating a polymer regarding the content and migration potential of its oligomers several factors like the separation of oligomers from the material, the choice of suitable separation and detection techniques for identi?cation and quanti?cation and the choice of an appropriate standard have to be considered. Generally, MS technologies coupl
