Courtesy of Sigma-Aldrich Co., LLC

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
