In Chapter One, the specific patterns and applications of micro extraction techniques in bionalysis are reviewed. The various micro-extraction techniques can be classified into two rudimentary categories: solid-phase micro-extraction and liquid-phase micro-extraction, which are derived from conventional solid-phase extraction and liquid-liquid extraction, correspondingly. Next, an overview of the application of solid-phase micro-extraction in assessing target chemical families in different alcoholic beverages is provided. The results re-count the last 10 years of scientific publications, concentrating on the extraction conditions used for investigating different compounds in wines, beer and spirits according to the chemical families. Additionally, the authors discuss optimisation strategies for achieving accurate quantification. Chapter Three presents research on solid phase micro-extraction its advantages. Since solid phase micro-extraction was presented in the early 1990s, there has been an increase in research on new methodical solutions in many research facilities around the world that could potentially increase use of this technique. In Chapter Four, modern uses of new sorbent coatings in solid-phase micro-extraction are analysed. The combination of molecularly imprinted polymers with solid phase micro-extraction results in a possible technique for sample preparation, predominantly considering their described success in recent literature.
