Looking through publications on electromembrane extraction (EME), it is somewhat unclear if matrix ions in the sample affect the extraction of the compounds of interest. Recently, we have looked into this very fundamental question...

For electromembrane extraction of polar substances, we need a carrier in the liquid membrane. Often, we use di(2-ethylhexyl) phosphate (DEHP) as carrier, but do we really know how this is working? This question we investigated recently in very fundamental work...

During electromembrane extraction (EME), electrolysis inevitably takes place in the aqueous sample and acceptor, by oxidation and reduction of water. Due to this, pH may change, and the system becomes less stable. Recently, we developed an AgCl electrode for EME to avoid pH changes. With our new electrode, electrochemistry takes place on the electrode surface rather than in water…

The last year has been very intensive in terms of writing reviews. Together with international collaborators, we have reviewed “emerging extraction strategies” for Analytical Chemistry, “microextraction in bioanalysis” for Journal of Chromatography A, “hollow-fibre liquid-phase microextraction” for Journal of Pharmaceutical Analysis, and finally “mass spectrometric measurements from organ-on-chip systems” for Electrophoresis. For us it has been a great opportunity to get fully updated in areas where we are doing experimental work… Hopefully, many scientists will find valuable information and inspiration in the reviews...

Wuhan has been in focus the last couple of months due to virus, but Wuhan is also a very active spot in development of electromembrane extraction (EME). Collaboration with this Chinese EME hub is extremely important, and one example was published recently in Journal of Membrane Science…

Smartphones will be very important for chemical measurements in the future. For patients, smartphones may be used to check that they are properly medicated, based on measurement from a single blood droplet obtained by a finger prick. Concentration measurement of drugs, they can do themselves in the future, provided that small devices are developed, where the drug substances are separated from all the other compounds present in blood, before measurement. In our newest research, we took a small step in this direction…
