Popis: A pulse dilution system in which small volumes of gas are injected into an air flow, by means of a standard 6-port G. C. valve, is described. This system is shown to produce the expected dilution, and to be able to produce gas mixtures whose concentrations can be varied by an order of magnitude simply by varying the injection frequency.
