ABSTRACT:
Gas cylinders are filled with mixtures of gases comprising a minor component, which is to be present in the mixture at a concentration of 10% or less of the total volume of the cylinder, and a major component, which is to be present at a concentration greater than about 10% of the total volume, by charging the lighter component into a chamber of given volume to a pressure and at a temperature such that the volume provides the desired fraction of minor component in the gas mixture, and then flushing the minor component into the cylinder using major component gas as the flushing agent. The pressure at which the minor component volume is to be measured is preferably at or near the final pressure of the filled gas cylinder.
