摘要：

Ultrasmall-volume measurements of oxidizable compounds have been accomplished by coupling a capillary flow injection system with amperometric detection. Remarkably low (femtomole) mass detection limits result from the combination of nanoliter sample volume and the inherent sensitivity of the wall-jet detector. A substantial economy of reagent consumption and disposal accrues from the operation of the nl/min flow regime. Variables influencing the physical dispersion in the capillary how injection system, including capillary length, sample volume or flow rate, are explored and optimized.
