Multiple determinations with moving-boundary electrophoresis.

OVING-BOUNDARY BLECTROPUORESIS is a widely used technic for the investigation of colloidal systems. A limitation of this method, however, is the considerable amount of time required for a single experiment. It is particularly time consuming where the accumulation of large amounts of data is necessary. Furthermore, in the majority of instruments only 1 experiment at a time, and usually a total of only 2-3 per day, can be performed. In a previous publication (1) an electrophoresis cell was described in which two determinations can be performed simultaneously. Using such dual-analysis cells, the authors have developed a procedure for multiple electrophoretic analysis which permits up to 12 such experiments to be performed in an 8-hour day.
