[en] The optimal design of experimental separation processes for maximum accuracy in the estimation of process parameters is discussed. The sensitivity factor correlates the inaccuracy of the analytical methods with the inaccuracy of the estimation of the enrichment ratio. It is minimized according to the design parameters of the experiment and the characteristics of the analytical method

[en] The process for separating a beam of molecules according to mass and/or size of its components is characterized by the fact that the beam of molecules is deflected as transverse beams by one or more auxiliary gas jets. (orig./MM)

[en] The general characteristics and possible uses of electrophoretic separation methods in radiochemistry are given. The brief survey of the physical fundamentals of this method includes the principal quantitative relations, including correction factor for the effect of the porous carrier allowing the assessment of optimal conditions for the separation of different ions. Examples are given for different electrolytes used in the electrophoretic method in radiochemistry. A survey is given of the basic procedures applied in electrophoretic separation. Main attention is devoted to different types of single and continuous separation applied in laboratory work. (L.K.)
