ABSTRACT:
A trace component dispensing system where a trace fluid in fluid is introduced into a carrier fluid by use of a controlling permeation member where the carrier fluid and trace fluid are continuously flowing and the trace fluid is transferred on at a selected permeation rate to the carrier fluid. In another aspect, tracer fluid dispenser capable of outputting a fixed rate of flow is utilized to input to a fluid in a fixed volume container for a predetermined period of time to establish a desired concentration of the trace fluid in the fixed volume container where the desired concentration is a function of the fixed rate of flow and the fixed volume container.
