Abstract

A method for filling a batch of gas bottles with a gas mixture, wherein the gas mixture may have of a single constituent in a matrix or a plurality of constituents in a matrix, which matrix has of one or more base gases, in which a real-time analysis of all the constituents of the gas mixture is carried out at the exit of a mixing chamber and before it enters a compression stage.
