Abstract
An improved device was proposed for the fractionation and preconcentration of particles and macromolecules. The device provides new means for the separation of water components. In the proposed method, a tangential flow of the test solution is passed through a series of successive membranes with decreasing pore size. The method was applied to the fractionation of low-mineralized water (Ty va Arzhaanes) with low concentrations of trace components.
