Dispersive and Magnetic Solid-Phase Extraction of Organic Compounds: Review of Reviews.

Dispersive solid-phase extraction (DSPE) and magnetic solid-phase extraction (MSPE) are methods of solid-phase sorption preconcentration. Compared to classical solid-phase extraction, these methods have a number of advantages, such as reduced consumption of sorbents and solvents, extraction time, and cost of analysis. The popularity of the method among the analysts is evidenced by the large number of reviews we have summarized in this publication. Information is systematized on different versions of these methods, differing in the way the preconcentration process is carried out, the nature of the sorbents used, and their combination with methods for the subsequent determination of the preconcentrated substances; examples of using DSPE and MSPE for the separation of organic compounds in the analysis of environmental samples, food products and biological fluids are given.
