Summary: Solid-phase microextraction (SPME) is a widely used sample preparation technique that is simple, effective, and environmentally friendly. By coupling SPME with MS, rapid determinations and automation are enabled. The direct coupling of a high-throughput SPME system and MS allows for fast screening and quantitation with short analysis times. Furthermore, this combination reduces the consumption of organic solvents or gas, making SPME-MS even more environmentally friendly.

Summary: Recent research has shown that there are multiple types of hydrogen bond interactions in deep eutectic solvents (DES) and DES-water mixtures, which are crucial for the formation of DES. In addition, van der Waals interactions also play a role in stabilizing DES structures and lowering their melting points. However, excessive water can disrupt the most important hydrogen bonds in DES, leading to structural destruction.

Summary: About 20 years ago, Abbott and co-workers researched new solvents based on mixtures of choline chloride with urea and carboxylic acids, which were liquid at ambient temperature. These mixtures were later named deep eutectic solvents (DES) and quickly gained attention in chemical and materials research. Different definitions of DES have been proposed, leading to differing views among researchers. A phase diagram is needed to correctly assign a solvent to the DES or eutectic solvent (ES) group, based on deviation from ideality and liquid window. It is important for authors to use the terms DES or ES accurately in publications to further develop the utilization of these solvents.
