TL;DR: Ionic liquids (ILs) are a highly unique class of non-molecular solvents that possess melting points below 100 ºC and possess a wide variety of unique physico-chemical properties, including low or negligible vapor pressure at room temperature, high thermal and electrochemical stability, and high conductivity.
Abstract: Ionic liquids (ILs) are a highly unique class of non-molecular solvents that possess melting points below 100 ºC.1 ILs that have melting points below room temperature are often referred to as room temperature ionic liquids (RTILs). ILs possess a wide variety of unique physico-chemical properties, including low or negligible vapor pressure at room temperature, high thermal and electrochemical stability, and high conductivity.2.

TL;DR: In this article , the authors present a road map for the development of overall greener analytical methodologies and highlight the importance of applying green metrics for assessing the greenness of sample preparation methods, next to the contribution of GSP in achieving the broader goal of sustainability.
Abstract: The ten principles of GSP are presented with the aim of establishing a road map toward the development of overall greener analytical methodologies. Paramount aspects for greening sample preparation and their interconnections are identified and discussed. These include the use of safe solvents/reagents and materials that are renewable, recycled and reusable, minimizing waste generation and energy demand, and enabling high sample throughput, miniaturization, procedure simplification/automation, and operator's safety. Further, the importance of applying green metrics for assessing the greenness of sample preparation methods is highlighted, next to the contribution of GSP in achieving the broader goal of sustainability. Green sample preparation is sample preparation. It is not a new subdiscipline of sample preparation but a guiding principle that promotes sustainable development through the adoption of environmentally benign sample preparation procedures. • The ten principles of green sample preparation are presented. • Sustainability issues on solvents, reagents and materials are considered. • Fast, miniaturized, automated, in situ and low-energy methods are preferred. • Post-sample preparation configuration for analysis is considered. • Green metrics and the impact on sustainable development are discussed.

TL;DR: This Review focuses on the applications ofILs and IL-based sorbents in sample preparation with a special emphasis on liquid phase extraction techniques using ILs and MILs, IL- based solid-phase extraction, ILs in mass spectrometry, and biological applications.
Abstract: The applications of ionic liquids (ILs) and IL-derived sorbents are rapidly expanding. By careful selection of the cation and anion components, the physicochemical properties of ILs can be altered to meet the requirements of specific applications. Reports of IL solvents possessing high selectivity for specific analytes are numerous and continue to motivate the development of new IL-based sample preparation methods that are faster, more selective, and environmentally benign compared to conventional organic solvents. The advantages of ILs have also been exploited in solid/polymer formats in which ordinarily nonspecific sorbents are functionalized with IL moieties in order to impart selectivity for an analyte or analyte class. Furthermore, new ILs that incorporate a paramagnetic component into the IL structure, known as magnetic ionic liquids (MILs), have emerged as useful solvents for bioanalytical applications. In this rapidly changing field, this Review focuses on the applications of ILs and IL-based sorbents in sample preparation with a special emphasis on liquid phase extraction techniques using ILs and MILs, IL-based solid-phase extraction, ILs in mass spectrometry, and biological applications.
