ABSTRACT:
Cell useful for equilibrating a hydrophilic liquid such as an aqueous solution held therewithin with a gas composition. The cell comprises a tube having an open end and a closed end, the closed end comprising a porous member having a hydrophobic surface, the member being impervious to flow of a hydrophilic liquid therethrough when the tube is filled therewith and positioned vertically with a closed end thereof downwardly and being permeable to pressurized flow of the gas composition upwardly therethrough. The invention is also concerned with such a cell in an apparatus for equilibrating a hydrophilic liquid such as an aqueous solution with a gas composition, which apparatus comprises a gas vessel having therewithin a gas of a selectable composition at a pressure above ambient atmospheric pressure, flow control means for receiving flow from said vessel and controlling a flow rate therefrom and conduit means leading from the flow control means to a solution cell having therewithin a hydrophilic liquid.
