Process for separating substances of different masses

摘要

A process for separating substances of different masses, comprising admission of at least two fluids to one end of a duct arranged so as to allow a laminar flow of fluids so admitted, at least one of these fluids being periodically admitted into said duct and being comprised of a mixture of n substances of different masses, in being equal to at least 2, and collecting from the other end of the duct those fractions of the fluid mixture, wherein average relative concentration of at least one of the substances of the mixture of n substances is higher than in said admitted mixture.
