- The sample preparation stage is a critical step in the whole analytical procedure as it often determines the efficiency of the process. What is particularly noticeable in the area of biological samples. Blood, milk, urine, saliva or tissue are only few examples of complicated biological matrix, that require a optimization of sample pre-treatment method for particular analytes. For these purpose, the aim of following chapter was to characterized main problems with sample preparation method as well as highlighted some innovative ways how to improve sample preparation stage. Attention was particularly focused on the use of dispersive solid phase extraction (dSPE), which has achieved high growth in interest in recent years, mainly due to the simplicity and rapidity of performance. This method is not only used with commercially available sorbents, but also provides a basis for trying to apply new analytical tools for separation of analytes from matrix. Following the trends of nanotechnology and within the rules of green analytical chemistry, scientists are facing the challenges of determining and identifying compounds from various chemical groups. Frequently targeting analytes at trace concentration levels as well biological samples. In addition, attention is also focused on reagents reduction and shorter analysis time but also in terms of minimization of sample volume, which should to be collected. Herein the chapter presented describes exemplary new proposals in sorbents such as molecularly imprinted polymers (MIPs), supported ionic liquids (ILs), dendrimers and metal-organic framework (MOFs). In addition, it also looked at the potential use of magnetic nanoparticles as carriers. New sorbents in sample preparation together with modem instrumental techniques therefore allow the development of a procedure that will be characterized by high selectivity and specificity.
