Abstract: The present invention relates to a method for producing and delivering a gas mixture having a selected composition of a first gas and at least one second gas, comprising the following steps: (a) providing a main gas flow comprising the first gas in a main conduit, (b) separating the main gas flow into a first plurality of secondary gas flows, (c) guiding each secondary gas flow through a secondary conduit, (d) adding at least one second gas to at least one of the first plurality of secondary gas flows in the respective secondary conduit through a delivering conduit, said delivering conduit protruding into the secondary conduit, and (e) combining the first plurality of secondary gas flows to the gas mixture. With the technical teaching of the present invention a dynamic gas bottle filling is possible wherein the second gas components may have a concentration form some ppb to percent.

Abstract: Method for filling at least one compressed gas tank with at least one gas, wherein a reference pressure gas tank is formed in which a measurement can take place of at least one measurement variable which is relevant for the state in the reference pressure gas tank, wherein the compressed gas tank and reference pressure gas tank are flow-connected at least at times, wherein each compressed gas tank and the reference pressure gas tank have in each case one opening through which a gas can be filled and extracted, wherein in a filling process, at least one gas is filled through the opening into the at least one compressed gas tank and at least at times into the reference pressure gas tank, is characterized in that a measuring sensor is inserted through the opening into the reference pressure gas tank, and at least one measurement variable is measured by the measuring sensor at least during a part of the filling process.
