ABSTRACT:
Multiple electropherograms or chromatograms representing successive stages of an electrophoretic or chromatographic separation in a capillary are obtained by training a recorder on a succession of detection windows in the capillary, spaced apart along the capillary length. A single immovable detector is used, and the capillary is either held such that each detection window is placed in alignment with the detector in succession, or is looped such that the detection windows all lie in the path of the detector at the same time.
