Prepare Olive Oil Samples for Pesticide Residue Analysis in Half the Time with a Fraction of the Solvent Using dSPE

Olive oil is considered a healthy fat source and is a staple in many recommended diets. However, concerns about potentially negative health effects associated with pesticide residues have increased consumer interest in testing. There are several existing methods for measuring pesticide residues in olive oil, all of which involve sample extraction and cleanup. The common goal of these methods is to remove lipids that are harmful to the analytical system. Efficient sample cleanup procedures are critical to maximizing sample throughput and minimizing labor and material costs. This application note demonstrates the efficiency of a dSPE cleanup procedure, as well as the capabilities of a method-specific analytical column.
