Abstract
The invention is directed to an arrangement for generating a gas mixture. The arrangement includes a vaporizer which is switched into a vaporizer line which starts at a supply line and opens into a user line with the vaporizer line being bridged by a bypass line. The influence of material parameters associated with the metering of the vaporized gas quantity is reduced. For this purpose, the vaporizer line is alternately interrupted at the input and the output of the vaporizer and, when interrupted at the output side, the user line is interrupted by means of a switching element arranged therein.
