The history of process gas chromatography is described briefly, followed by a description of the essential details of process gas Chromatograph systems. The economics of process analysers are contrasted with those of laboratory instruments, and the application of process analysers to automatic control systems, process control computers and data loggers or chemical plant is discussed. The paper concludes with a discussion of likely future trends in the subject.
