Abstract: The present invention relates to an emulsion, preferably a water-in-oil emulsion. comprising: a continuous phase comprising a conductivity improving compound, a dispersed phase suspended in the continuous phase, and a surfactant. The present invention also relates to a population of droplets comprising an aqueous phase, dispersed in a continuous oily phase comprising an oil and a conductivity-improving compound. The present invention also relates to a microfluidic chip comprising a hydrophobic composition comprising an oil, a surfactant and a conductivity improving compound in an injection chamber configured so that injecting a hydroplilic composition through said injection means will generate an emulsion in the injection chamber; and to a kit comprising a microfluidic chip and a container comprising an aqueous composition. The present invention also relates to a process for manufacturing an emulsion according to the invention.
