Gas mixture e.g. tertiary gas mixture, producing method, involves determining pressure in gas container and flow technically connecting storage container with gas container until pressure in gas container reaches predetermined value

摘要

The method involves determining the pressure in a gas container (1), where a main component and a secondary component are present in a storage container (18). The storage container is flow technically connected with the gas container until the pressure in the gas container reaches a predetermined value. A filling pipe (3) provided between the storage container and the gas container is evacuated before connection to the storage container. A reference container (2) is connected to the gas container, where measurement takes place in the reference container. An independent claim is also included for a gas mixture production device comprising a filling pipe.
