ABSTRACT:
A method and analyzer for monitoring the progress of a chemical process in which a fixed volume sample of the reactive mixture of the chemical process is periodically gathered and injected into a fluid stream of a liquid carrier. The sample in the liquid carrier is passed through an infrared detector which detects the amount present in the sample of a species of the reaction mixture which is indicative of the progress of the chemical process.
