ABSTRACT

Key to the success of gas chromatography as a separation technique are the advances, some small and some large, in the evolution of the instrumentation. A basic instrumental layout for a capillary gas chromatography (GC) instrument is shown in Figure 2.1. The main instrumental components of a gas chromatograph are

• Gas supply • Sample introduction system • Column oven • Column • Detector • Read-out device, typically a computer with appropriate software

that allows, as a minimum, integration and display of peak area and peak height. In addition, it is likely that a host of other variables are available that contribute to the determination of more fundamental parameters (e.g., retention time), as described in Chapter 3.
