Abstract
The apparatus and method of the present invention disclose a system in which multiple injections may be made into a capillary array. The injections are spaced in time with each injection followed by an interval of electrophoresis. Once all samples are loaded into the capillaries, continuous electrophoresis and detection is used to separate and detect target compounds within the sample. The interval between injections is matched to the target compound migration rate to be sufficient to allow the target compounds to be detectably separated when the compounds reach the detector.
