Solid phase microextraction is one of the most popular green techniques used for sample preparations in analytical chemistry. It is a simple, rapid, sensitive, and solvent-free technique. Since SPME was first introduced in the early 1990s, there has been an intensification of research in order to elaborate new methodical solutions in many research facilities around the world, which could increase the use of this technique. More robust fiber assemblies and coatings with higher extraction efficiencies, selectivity and stability have been commercialized. Moreover, automation and on-line coupling to analytical instruments have been achieved in many applications. Furthermore, devices using tubes, needles or tips for extraction instead of a fiber have been designed. It also needs to be mentioned that improved calibration procedures have been developed to overcome existing limitations regarding quantitation. The numerous advantages of SPME means that it is almost universal, because it allows for the analysis of different samples in multiple physical states – liquid, gas and solid – often with very complex matrices, and it provides the determination of analytes at trace and ultra-trace levels. All those features make SPME a hot topic in the development of analytical chemistry and one of the most chosen techniques for sample preparation and analyte enrichment.
