METHOD AND APPARATUS FOR DYNAMIC GAS MIXTURE PRODUCTION

摘要

The present invention relates to a method and an apparatus for producing and delivering a gas mixture having a selected composition of a first gas and at least one second gas. The method comprises the following steps: a) providing a main gas flow comprising the first gas in a main conduit (1), b) separating the main gas flow into a first plurality of secondary gas flows, c) guiding each secondary gas flow through a secondary conduit (2), d) adding at least one second gas to at least one of the first plurality of secondary gas flows in the respective secondary conduit (2) through a delivering conduit (3), said delivering conduit (3) protruding into the secondary conduit (2), 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.
