A model of mass transport near the tube wall in a flow-injection manifold

The time dependence of analyte concentration at the surface of a flow-by potentiometric sensor in the flow-injection analysis was investigated theoretically. The relationships between the properties of response and experimental parameters, such as the sample volume and the distance between the injection point and the sensor, was calculated by finite difference numerical simulation.
