On the other hand, a suitable disperser solvent has to be miscible with both aqueous and organic phases in order to ensure the formation of the cloudy state that enhances the contact between two phases, thus facilitating extraction. However, at the same time, the disperser solvent can complicate the process of phase separation. For this reason, centrifugation — which is considered to be the method's most time-consuming step — needs to be applied in the majority of conventional DLLME procedures. Moreover, centrifugation of larger volumes is simply too difficult to carry out [16].
