For the extraction of a gas sample from a container (1) a gas flow (3) is introduced into the container, expelling from the container gas contained therein. The expelled gas (5) is introduced into a collecting chamber (4) with an inflow opening larger than the outflow opening. Above the outflow opening, a suction pipe (7) extracts a portion (8) of the gas flow expelled from the container and supplies it to an analysing station for analysis. This method and arrangement enable the expelled gas flow to be utilized for a longer time without significant dilution, thus affording better conditions for analysis.
