Electrophoresis method and apparatus with time- or space-modulated sample injection

摘要

A detection apparatus comprising a separation channel (20) into which a sample comprising different components is introduced. The apparatus is provided with means (22, 24) for introducing the sample into the separation channel with a series of predetermined separations. The components are transported along the separation channel such that the different components travel at different speeds. A plurality of temporally or spatially distinct signals are generated, each representative of transport of one component past at least one fixed point in the channel. The signals are correlated to derive frequencies characteristic of the speed of travel of the components.
