PFAS in Food, Feed and Biota - Sampling and Sample Preparation
A major part of the variance in the analytical chain comes from sampling and sample preparation. They are thus of great importance for achieving a correct and representative result. Although sampling is typically outside the laboratory’s “control” there is still a need for guidance not at least in relation to conditions for preparation and analysis. This may concern basic issues such as sample weight and containers. Likewise, sample preparation is a field where information is required to understand what is applicable and what is possible to perform.
Regarding PFAS in food, biota and feed, Eurofins receives numerous questions relating to these areas both from a food/feed and an environmental perspective. We have therefore chosen to produce an information sheet where our capacity for sample preparation for these matrices is outlined. This concerns e.g. mixing, filleting, peeling and composite samples. Moreover, some guidance on sampling with reference to published documents is given. Information on optimal and minimal sample weights together with containers is also included.
