Recent Trends in Pharmaceutical Analytical Chemistry

Background: Ionic liquids (ILs) are a unique class of compounds consisting exclusively of cations and anions that possess distinctive properties such as low volatility, high thermal stability, miscibility with water and organic solvents, electrolytic conductivity and non-flammability. Ionic liquids have been defined as "design solvents", because it is possible to modify their physical and chemical properties by appropriately choosing cations and anions, in order to meet the specific characteristics based on their potential application. Introduction: Due of their tunable nature and properties, ILs are considered as the perfect candidates for numerous applications in analytical chemistry including sample preparation, stationary phases in liquid or gas chromatography, additives in capillary electrophoresis, or in mass spectrometry for spectral and electrochemical analysis. In the last years, the number of publications regarding ILs has rapidly increased, highlighting the broad applications of these compounds in various fields of analytical chemistry. Results: This review first described the main physico-chemical characteristics of ionic liquids, and subsequently reported the various applications in different subdisciplines of analytical chemistry, including the extraction procedure and separation techniques. Furthermore, in each paragraph the most recent applications of ionic liquids in the food, environmental, biological, etc. fields have been described. Conclusion: Overall, the topic discussed highlights the key role of ionic liquids in analytical chemistry, giving hints for their future applications in chemistry but also in biology and medicine.

Abstract The tools of analytical chemistry, and the expertise and enthusiasm of many of its practitioners, have had a profound influence in the field of cultural heritage [1, 2]. Analytical techniques, especially those involving non-destructive methods of examination, have played a key role in the characterization, restoration, and preservation of an incredible range of works of art and cultural heritage, including ceramics, textiles, paintings, books, drawings, sculptures, jewelry, and a myriad of artifacts made of glass, wood, or metal. In addition, modern analytical instrumentation has been successfully applied to study the techniques used to produce heritage materials, to verify the authorship or estimate the date of pieces of art, and to detect reproductions and forgeries.
