Solid-phase extraction of these compounds on reversed-phase srrrbents is an attractive alternative to more traditional methods that utilize liquid/liquid extraction for the removal of these herbicides from aqueous samples. The hydrophobic reverse phase filler can retain most of the non-polar compounds and most of the organic analytes in the aqueous matrix. The digestion protocol can be continued with a peptide purification step by means of SPE, generally in the form of a reversed-phase C18-tip.
