<p>The invention relates to a method for the identification of substances, the determination of their molecular characteristics and the handling of said substances for isolating or concentrating them from mixtures or solutions. The inventive method involves: generating a flow of particles from a mixture or solution with dipolar electrical or magnetic moment; exposing said flow to a homogenous electrical or magnetic field and simultaneously to a perpendicular oscillatory electromagnetic field; measuring the number of flow particles. When radiation is resonant between two quantic levels, a variation in the population of the quantic levels affected by the quantic transition is detected. Said variation in the number of molecules is translated into a variation of the detector signal and makes it possible to determine the concentration of a substance in a sample. Separation of the substance is achieved by selecting the resonant frequency for said substance.</p> |
