6 Drying or Concentrating Extract Solvent removal from the extract is commonly carried out using evaporation, vacuum concentration, lyophilization, etc. The objective of solvent removal is to preserve the solute. The removal of solvent can be accomplished effectively by boiling. Solvent can be boiled off either by applying heat or by lowering the atmospheric pressure. In both cases, the energy of molecular motion is greater than the intermolecular forces holding the molecules in the solution, and as a result solvent molecules move from liquid phase to gaseous phase.

In closed-vessel extractors, the vessel containing the sample and solvent is closed, whereas in FOV-MAE it is open. In the case of CV-MAE, extraction is carried out under controlled pressure and temperature increase is achieved rapidly. Pressure depends on the volume and boiling point of the solvent as the solvents may be heated to about 100°C above their boiling point under atmospheric conditions in CV-MAE. The temperature can be fixed by adjusting the microwave power (100–1000 W), and power should be suitably chosen to avoid overheating, leading to degradation of analyte and overpressure.
