The complexity of food matrices often requires tedious and time-consuming sample preparation strategies that often are a source of a significant amount of laboratory waste. The development of a new matrix-compatible solid-phase microextraction (SPME) coating, namely PDMS/DVB/PDMS, bearing enhanced antifouling properties, enabled the analysis of complex food matrices by direct immersion SPME (DI-SPME) and helped to overcome issues related to extensive sample pre-treatment and instrumental contamination. This webcast will focus on recent advances made toward the analysis of contaminants in complex food samples by using the new matrix-compatible SPME coating and will describe the optimization of important parameters to be considered when performing DI-SPME.
