Provided is a novel system and apparatus (200) for producing primary standard gas mixtures. The system includes providing a gas permeation device (210) having a constant diffusion rate into a temperature controlled enclosure (220); connecting a supply source (230) of a component to the permeation device (210); routing the component from the gas permeation device (210) to a product container (290) until a desired amount of said component in the product container (290) is reached; and supplying a balance of purified gas to the product container (290) to obtain a known concentration of component in the primary standard gas mixture.

L'invention concerne un système et un appareil (200) nouveaux pour la production de mélanges gazeux classiques primaires. Le système consiste à insérer un dispositif de perméation de gaz (210) présentant une vitesse de diffusion constante dans une enceinte à régulation de température (220) ; à relier une source d'alimentation (230) d'un composant au dispositif de perméation (210) ; à acheminer le composant depuis le dispositif de perméation de gaz (210) vers un contenant de produit (290) jusqu'à atteindre une quantité souhaitée dudit composant dans le contenant de produit (290) ; et à alimenter un équilibre de gaz purifié dans le contenant de produit (290) afin d'obtenir une concentration connue de composant dans le mélange gazeux classique primaire.
