Abstract
A package containing a reference liquid for the calibration and/or quality control of blood gas analyzers. The reference liquid is enclosed in a flexible, gas-tight container without any gas bubbles in the container, and to avoid any danger of formation of gas bubbles, the total gas pressure in the liquid is kept below 600 mm Hg at 37° C. The container is preferably a laminate bag of aluminum foil with interior layer of heat sealable plastic of low gas permeability, preferably a polyacrylonitrile copolymer.
