WebMixtures of water or aqueous buffers and organic solvents are used to elute analytes from a reversed-phase column. [2] The solvents must be miscible with water, and the most common organic solvents used are acetonitrile, methanol, and tetrahydrofuran (THF). Other solvents can be used such as ethanol or 2-propanol (isopropyl alcohol). Weball deep eutectic solvents are hydrophilic and are limited in applications that require high basicity and low water content such as liquid–liquid extraction (LLE).
