Direct coupling of supported liquid membranes to capillary electrophoresis for analysis of complex samples: A tutorial

• Direct coupling of SLM based extractions to CE is critically evaluated.
• Various instrumental set-ups and their practical applicability are discussed.
• Coupling of SLMs to lab-made, commercial and microchip CE is described.
• Other membrane based extractions coupled to CE are also evaluated.
• Adaptation of these set-ups for use with SLMs is comprehensively discussed.

This tutorial provides an overview of direct coupling of extraction techniques based on supported liquid membranes (SLMs) to capillary electrophoresis (CE) for treatment and subsequent analysis of complex samples. Pros and cons of using each of the described instrumental arrangement are addressed and where relevant, comments with personal experience of the authors are presented. Solid porous membrane based extraction techniques coupled directly to CE are also presented in this tutorial and a comprehensive discussion is included on their instrumental set-ups and their possible adaptation for use with SLMs.
