Extensive clean-up procedures are normally required to remove matrix components which may interfere in the analysis. Some common strategies to these steps are based on the liquid–liquid extraction or solid phase extraction (SPE) techniques, in which the separation occurs by the analyte partition coefficientbetween the sample solution phase and the solid sorbent. SPE has several merits such as lower cost, higher enrichment factor and less consumption of organic solvents.
