ABSTRACT:
Gas generating apparatus in which a supply of carrier gas is mixed with an impurity gas that permeates through the membrane of an impurity gas generator. A dopant gas is supplied to the impurity gas generator through a pressure controller which operates in response to a pressure monitor that monitors the pressure of the dopant gas supplied to the impurity gas generator. As the monitored pressure of the supplied dopant gas changes, the pressure of that supplied gas likewise changes in a manner which maintains a substantially constant flow rate of the impurity gas through the membrane to be mixed with a carrier gas.
