DLLME is based on (i) the rapid injection of an appropriate mixture of two solvents — one acting as an extraction solvent and the other as a disperser solvent — into a sample solution with a syringe; (ii) the formation of a cloudy solution containing fine droplets of extraction solvent fully dispersed in aqueous phase; and (iii) subsequent centrifugation, which causes the accumulation of the extraction phase at the bottom of the extraction vessel
