Looking back into research papers on electromembrane extraction (EME), a jungle of different liquid membranes has been used, and they have been developed more or less by trial-and-error type of experiments. The last year, we have put a lot of efforts into standardizing stable and efficient liquid membranes, to propose generic extraction conditions to bases and acids of different polarity. A recent paper is one contribution in a series of papers, where we have optimized generic conditions for basic substances with low and moderate polarity

We have for long time been investigating electromembrane extraction (EME) of peptides, in a large research project funded by the Research Council of Norway. Peptides are difficult because they have very poor partition into the liquid membrane. However, by testing a large number of liquid membrane compositions, we have learned that deep eutectic solvents show great potential. The deep eutectic solvents we prepare by mixing two solid substances together, and with a magical touch, we have a liquid that works superbly for peptide extraction!
