Advances in stir bar sorptive extraction coating: A review

Summary Stir bar sorptive extraction (SBSE) is an extraction technique for enrichment of organic compounds from aqueous and gaseous matrices. This technique is based on sorptive extraction, whereby the solutes are extracted into a polymer coating on magnetic stirring rod. SBSE has been used in various types of analytical procedures and wide variety of matrices. However, a limitation of SBSE lies in the fact that only polydimethylsiloxane (PDMS)-coating material is commercially available and that PDMS predominantly extracts non-polar compounds with Ko/w higher than 10. In this survey, a review on non-PDMS stir bar sorptive extraction coatings and their applications to the analysis of environmental, food, and biomedical samples is given.
