Abstract
A method and an apparatus for determining the coverage of the interface between a liquid first phase and a liquid or gaseous second phase by at least one molecular species, at least the following procedural steps being carried out successively: the generation of a stream of droplets which contain at least the liquid first phase, in such a way that the droplets move along a droplet trajectory, and the non-contact determination of a measure of the coverage of the interface by the at least one molecular species at at least two different points along the droplet trajectory.
