MIP SPE was successfully used for extraction of multiple classes of food and environmental contaminants from difficult matrices, such as egg, oil and flour.
• Six nitroimidazoles were extracted from egg and milk with recoveries typically over 90%.
• Among NSAIDs compounds, acidic compounds gave good recoveries between 100-115% while non-acidic compounds gave less desirable recoveries from water.
• Extraction nine PAHs with four or more rings from oil resulted in most of the recoveries over 80%.
• More hydrophobic ergot alkaloids gave better extraction and reproducibility
