Abstract
Apparatus for electrophoretic analysis of ions or like electrically charged particles, wherein the potential gradients of the different kinds of ions contained in a liquid column formed in an electrophoretic capillary tube are detected and the ratio between potential gradient of a selected one of said different kinds of ions and that of each of the other kinds of ions is calculated to obtain a value relating to the mobility of each of said different kinds of ions.
