From the sorption-based methods available nowadays, stir bar sorptive
extraction (SBSE) became a well-established analytical technique for sample
preparation, in which hundreds of applications in almost all scientific areas have
already been proposed in the literature. This remarkable analytical tool shows great
capacity for static microextraction and outstanding performance to operate at the ultratrace
level, in particular for the analysis of complex systems. Furthermore, is very
effective, present easy manipulation in comparison to other alternative techniques and
great reproducibility for the analysis of priority and emerging organic compounds.
Recently, related static microextraction techniques were introduced, with particular
emphasis to bar adsorptive microextraction (BAμE) that operates under the floating
sampling technology, in which has demonstrated high analytical capacity and
remarkable performance. This novel concept has also proved great effectiveness for
ultra-trace analysis of organic compounds with polar characteristics, in particular from
complex systems. The present contribution describes the fundamental principles, the
experimental methodology, the main applications, as well as, the analytical potential of
these novel microextraction techniques.
