Extraction of challenging polar substances...

Polar or water-soluble substances are abundantly present in the human body as both drug metabolites and endogenous metabolites. To extract the few we are interested in, from biological samples, is however a challenging task with most techniques, leaving us with limited options for analyzing these substances. In this overview article, we take the temperature on current efforts to apply electromembrane extraction (EME) for efficient and selective extraction of polar compounds.
