A method to adjust gas concentration in a fluid and a device thereof is provided. The method includes configuring a container of a second volume (VC) to receive a first volume (VL) of the fluid into the container. The second volume (VC) of the container is determined based on an initial concentration (Ci) of the first gas in the fluid, a target concentration (Cf) of the first gas in the fluid, a partition coefficient (φ) of the first gas, and the first volume (VL) of the fluid for obtaining the target concentration (Cf).
