Volumetric and gravimetric filling levels for producing mixed gases

摘要

The present invention is a method for producing a mixed gas in a gas container (B), wherein the mixed gas comprises a plurality of components, wherein at least one first component is volumetrically measured. The first component is then metered from the first component storage container (V1, V2, V3, VG1, VG2) to at least one sample volume (P1, P2, P3) of the plurality of sample volumes. , P4) and introduce from at least one sample volume (P1, P2, P3, P4) into the gas container (B), and at this time weigh the at least one second component gravimetrically At this time, at least one second component is introduced into the gas container (B) from the storage container (V1, V2, V3, VG1, VG2) of the at least one second component, and B) at least one second component To determine the rate of metered using a balance (W), to a method. The invention furthermore relates to an apparatus for carrying out the method according to the invention.
