Abstract: The invention relates to a process for treating, with a plasma, a composition comprising at least a first compound and a second compound, characterized in that said process comprises at least: generating, within an enclosure, a non-equilibrium plasma flow from a gas present in said enclosure, and treating the composition contained in said enclosure with said non-equilibrium plasma flow so as to extract at least a portion of said first compound.

Abstract: The invention relates to a process for selectively and continuously extracting a series of desired species from a matrix, comprising the steps of:—injecting a plasma (310) in an extraction chamber by means of a plasma torch,—continuously monitoring (320) the excited elements extracted from the matrix and contained in the plasma by optical emission spectroscopy, and for each species of the series,—setting a distance (330) between the support and the plasma torch, and the composition of the injected plasma as a function of the monitored excited elements so that only one desired species of the series of species is being extracted from the matrix under molecular form, and—providing (400) a plate in the extraction chamber, exterior to the plasma, causing collection of molecules comprising said desired species by deposition onto the surface of the plate.
