ABSTRACT:
An improved apparatus and method for the capillary electrophoretic separation of chemical compounds comprises carrying out on-line sample preparation by means of semipermeable membranes connected to the capillary separation column for selective introduction of ampholytes into the capillary separation column. Semipermeable membrane means may also be used on-line for preliminary desalting of the sample prior to its introduction into the separation column.
