摘要：

In flow-injection analysis (FIA) systems with electroosmotic flow (EOF), the maximum permissible sample throughput is a function of the electric field strength, capillary length and injection volume. The relation between the various parameters is theoretically and experimentally discussed Experimental results are in reasonable agreement with theoretical expectations. The potential of EOF pumped FIA using very short capillaries and relatively low applied voltages is discussed.
