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.
Des cylindres sont remplis de mélanges gazeux qui comprennent un composant minoritaire qui doit être présent dans le mélange à une concentration de 10 % ou moins du volume total du cylindre, ainsi qu'un composant majoritaire qui doit être présent à une concentration plus grande que 10 % du volume total, en chargeant le composant le plus léger dans une chambre à volume donné, à une pression et une température faisant que le volume fournisse la fraction voulue du composant minoritaire dans le mélange gazeux, et en vidangeant le composant minoritaire dans le cylindre à l'aide du composant majoritaire comme agent de vidange. La pression à laquelle le volume du composant minoritaire doit être mesuré est préférablement ou près de la pression finale du cylindre gazeux rempli.
