Abstract  

Analyzing environmental samples it is often necessary to determine traces in a matrix or to separate elements easily activated. In this case the detection limit depends on the amount of sample which can be separated. Frequently group separations are sufficient. In this paper we describe the relationship between amount, focussing area and concentration of the electrolytes in electrophoretic focussing. The load capacity and the possibility of group separations are evaluated. It is shown that within 4–5 min up to mg amounts can be separated into at least five groups on a 2 cm broad strip and that the ions are concentrated into small zones with a concentration of up to 1 mg·cm−2.
