Because the shape of this transient signal depends on the physical and chemical kinetic processes occurring in the carrier stream during the time between injection and detection, we include flow injection analysis in this chapter.

The retina in your eye, for example, is a transducer that converts photons into an electrical nerve impulse; your eardrum is a transducer that converts sound waves into a different electrical nerve impulse. A photon transducer takes a photon and converts it into an electrical signal, such as a current, a change in resistance, or a voltage.

In this section we develop a common vocabulary that we can use in later chapters.
