On the mobility of ions during electrophoresis in a homogeneous liquid and in porous media in the case of a linear dependence of the velocity on the amplitude of the electric voltage vector

Various types of mobility of inclusions and ions in a homogeneous liquid and in a porous medium filled with liquid are given, as well as the necessary definitions concerning the properties of porous media. The main attention is paid to ionic electrophoretic mobility in a homogeneous liquid and in a porous medium for the case of a linear relationship between the migration velocity and the amplitude of the electric field vector. The results concerning the determination of nucleotide mobility in various cases are presented. It is noted that in the case of a nonlinear dependence of the migration velocity on the amplitude of the electric field, the mobility ceases to be constant and becomes dependent on this amplitude. The results are useful for DNA sequencing researchers.
