Abstract
A method for measuring a concentration of a gas in a container having a wall with at least one deformable portion, the gas absorbing electromagnetic radiation at least in a specific spectral range, wherein the method includes the steps of biasing deformable portion and a further portion of wall opposite deformable portion between opposite positioning surfaces, thereby forming a biased volume of the container between the opposite positioning surfaces, during a measuring time, transmitting electromagnetic radiation into biased volume and receiving transmitted or reflected radiation of transmitted radiation from biased volume along respective radiation paths, relatively moving, during measuring time, at least one of deformable portion and of further portion and at least one of radiation paths, and determining concentration of said gas from the radiation received.
