WebA solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.Water is a solvent for polar … Webselectivity and extraction efficiency. This improvement can be attributed to the combination of temperature and pressure and the MSPD cleanup; also an important feature of this methodology is the minimization of solvent usage [37, 38]. Accordingly, extraction variables affecting analyte recovery have been optimized by a two-step experimental design
