title: Potential of the flow-gradient function in FIA with a multifunction pump delivery system.
abstract: By use of a multifunction pump delivery system with which any flow patterns are easily programmed, the potential of the flow-gradient function in FIA has been investigated. The mechanical stability and reproducibility of the pump system are very high because of the use of a central programming unit, and this enabled further and closer investigation of the function. A new parameter (dispersion volume) is proposed for evaluation of flow-gradient systems.
