Popis:	Reaction liquid is continuously circulated between the reactor and an automated Bendix liquid injection valve. A well defined volume of liquid is injected into a hot zone. The liquid injected is then vaporized and the resulting sample gas is swept with a stream of helium into a series of dilution chambers. The analyte concentration-time profile at the exit of the last chamber was mathematically modelled. It was found that the degree of symmetry of the profile increases when the number of chambers increases. The design and performance of the system are discussed together with results of a kinetic study of a chemical reaction.
