ABSTRACT:
A trace component dispensing system where a permeand in a container is exposed to an elongated permeation member in the container where the permeation member has a bore sized to control the rate of permeate flow. For low pressure application a tubing is inserted into the bore to pass carrier gas across the surface of the bore and to intermix with permeate. Fluids can be input to the container to block impurities from the permeate gas. The effective surface area can be controlled to control the rate of permeate flow.
