Disposable pipette tips extraction consists of a solid-phase extraction in which the sorbent is poorly dispersed in a pipette tip, which allows a quick and dynamic contact between the aspirated analyte from the sample and the solid phase. It is a technique used particularly in food and forensic analysis, since it requires a small amount of sample and solvent. This article highlights the principles, advantages and disadvantages of the disposable pipette tips extraction method and reviews recent applications.
1 Introduction
Sample preparation is still considered a bottleneck for the analysis of some compounds, especially in biological matrices, despite the advances in the chromatographic and detection techniques. Sample preparation methods have been constantly developed and optimized, with the aim of designing cheaper, faster, “clean” and effective approaches than those currently available. One of these recently developed methods is disposable pipette tips extraction (DPX), a promising SPE technique.
