Microextraction of drugs

This review will attempt to provide an overview as well as a theoretical and practical understanding of the use of microextraction technologies for drug analysis. The majority of the published reports to date focus on the use of fibre solid-phase microextraction and so the review is significantly focused on this technology. Other areas of microextraction such as single drop and solvent film microextraction are also described. Where there are insufficient examples in the literature to illustrate important concepts, examples of non-drug analyses are presented. The review is intended for readers new to the field of microextraction or its use in drug extraction, but also provides an overview of the most recent advances in the field which may be of interest to more experienced users. Particular emphasis is placed on the effect various sample matrices have on extraction characteristics.
