ABSTRACT:
Short capillary segments are introduced in succession into the current path of a capillary electrophoresis system, either at the downstream end of the separation capillary for purposes of collecting the eluting species in fractions, or at the upstream end for purposes of sequential sample loading. The segments are preferably contained in mobile cassettes whose motion is governed by either continuous or stepper motors at a controlled rate depending on which position the cassette occupies in the solute migration path.
