Abstract
For selective influencing of the ion mobility in CZE several electroly te additives were used. With acetone as organic solvent the migration times of inorganic cations are changed. The separation of Cl- and I- i s optimized by adding alpha-cyclodextrin to the electrolyte. By adding 18-crown-6 it is possible to slow down the mobility of K+. In this wa y the disturbing effect of matrix ions can be prevented.
