Flow Injection Analysis
Flow Injection Analysis
The focus of this section is on methods in which the signal is time-dependent. Methods based on the kinetics of chemical and nuclear reactions were presented in the previous two sections. In this section we consider the technique of flow injec- tion analysis. In this technique the sample is injected into a flowing carrier stream and swept through the detector, giving rise to a transient signal. The shape of this signal depends on the physical and chemical kinetic processes occurring in the car- rier stream during the time between injection and detection.
