    • 33.1: Overview of Automated Methods of Analysis
      An automated method of analysis is one in which the one or more steps in an analysis are completed without the direct action of the analyst. Instead, the instrument itself completes these actions. Some of these actions are carried out discretely and some are carried out continuously.
    • 33.2: Flow-Injection Analysis
      In this section we consider the technique of flow injection analysis in which we inject the sample into a flowing carrier stream that gives rise to a transient signal at the detector. Because the shape of this transient signal depends on the physical and chemical kinetic processes that take place in the carrier stream during the time between injection and detection, we include flow injection analysis in this chapter.
    • 33.3: Other Automated Methods of Analysis
      In the last two sections we introduced two examples of automated methods of analysis: a brief mention of automated titrators and a more extensive coverage of flow-injection analysis. In this section we consider three additional examples of automated methods of analysis: the stopped-flow analyzer, the centrifugal analyzer, and disposable single-test analyzers based on thin films, screen-printing, and paper.
