Abstract:

Sample introduction is a weak link in capillary electrophoresis (CE) systems, particularly when various pretreatments involving separation and modification of sample matrices are involved. Recently, the application of flow injection (FI) systems as a means of sample introduction and on-line sample pretreatment for CE has shown great potentials in improving the precision,reliability and throughput of CE systems. The advantages are discussed, illustrated by recent developments in the authors' group, including.
