J Chromatogr A. 2021 Mar 15:1640:461944. doi: 10.1016/j.chroma.2021.461944. Epub 2021 Jan 28.

Abstract

The development and application of alternative green solvents in analytical techniques consist of trends in sample preparation, since this subject represents an important step toward sustainability in experimental procedures. This review is focused on the main theoretical aspects related to deep eutectic solvents (DES), switchable hydrophilicity solvents (SHS) and supramolecular solvents (SUPRAS). Recent applications are highlighted, particularly for the extraction of different analytes from environmental, biological and food matrices. Moreover, novel configurations are emphasized, aiming for efficient, automated and high-throughput procedures. This review also provides some critical points regarding the use of these solvents and their green aspects.

Keywords: Deep eutectic solvents; High-throughput; Sample preparation; Supramolecular solvents; Switchable hydrophilicity solvents.
