Método y aparato para la producción dinámica de una mezcla de gases

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),
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.
