“…Therefore, µ-SPE has several benefits, including low solvent consumption, a higher enrichment factor than SPME, extremely high selectivity and sensitivity, simplicity of application, being less time consuming, a relatively low cost, compatibility with various systems of analyte separation and detection, and also enabling headspace and immersion modes. Despite all of this, there are drawbacks to the implementation of µ-SPE, including analyte carry-over, fragile fibres, and a stationary phase with a restricted range [60,95,96].…”
