WP-CBR001 - a new matrix-certified reference material to support food safety

Matrix-based certified reference materials (CRMs) play a key role in food contaminant analysis for ensuring measurement accuracy and comparability, as they exhibit the same matrix effects during sample preparation and measurement as the food sample under investigation. However, the availability of such CRMs is still limited. Therefore, there is a great need for the production and supply of new CRMs, which ultimately contributes to food safety.

The METAS presentation will offer an insight into the development of a new CRM, based on a whey protein powder, one of the most widely used food additives, for the determination of polycyclic aromatic hydrocarbons (PAHs) and toxic elements. With the aid ov applications from the METAS laboratories, we will demonstrate the advantages of using aforementioned matrix CRM. For example, we will illustrate the importance of choosing the most appropriate solvent for the extraction of PAHs in order to obtain correct results.
