Summary:Samples to be analysed and califration solutions for such analyses have a limited keepablity; they lose carbondioxyde and/or oxygen or take them up from the surrounding air. Analysing for several physiologically important parameters becomes unreliable. The invention provides a solution for this problem: glas syringes and cartridges capped with gas-impervious polymer, e.g. rubber. If desired they may be wrapped in an additional foil.
