Abstract:
Specific polarizability of bioparticles is, as a rule, much higher than that of inorganic particles. This difference makes up the basis for separating of different particles in the process of their sampling in the upper atmosphere and in space. The possibility of spatially separating particles further (after retarding) by making use of the difference in polarization is discussed. A device that is similar to the known mass spectrometer is proposed, but it operates with neutral particles instead of charged ones and a superposition of alternating electric and magnetic fields is used as a deflecting field. Under the exposure to an alternating electric field, the polarization current is induced, which interacts with the orthogonal phased-in magnetic field, and a particle occurs under the effect of a deflecting force proportional to the particle polarizability.
