Abstract

This thesis is based on the theory of Henry's criterion of sampling in the headspace area of volatile compounds by using solid microextraction under regular and vacuum conditions. In particular, the first chapter describes the basic principles of extraction, as well as the types of extractions. Moreover in this chapter there are the sampling methods and the various factors that may influence positively or negatively the extraction process. This chapter deals also with the theory of the extraction method used in the experiments and describes the characteristics and properties of the analytes. At the end of the first chapter, the aim of this thesis is being developed. The second chapter describes the experimental part of the project, mentions the reagents, instruments and devices that were used in the experiments as well as the experimental procedure. In the following chapters there are the results of the experiments and finally the discussion and the bibliography of the project.
