Electrically stimulated liquid-based extraction techniques in bioanalysis

Sample preparation is a vital and inseparable part of an analytical procedure. This issue has motivated the analytical research community around the world to develop new, fast and cost-effective extraction methods which can eliminate interfering substances, provide high preconcentration factors and increase the determination sensitivity. Electrical field induced extraction technique is a topic that has received major attention in recent years. This fact can be attributed to the considerable advantages provided by imposition of an electrical driving force especially control of different properties of an extraction system such as selectivity, cleanup, rate and efficiency. In this review, focus is centered...
