The invention relates to an oxygen scavenger/indicator which contains at least one substance with combined scavenger and indicator function for oxygen, which can absorb oxygen under the effect of moisture in basic conditions, and also to at least one basically reacting compound. The indicator effect is effected by a change in at least one physical property of the substance with combined scavenger and indicator function for oxygen, the change being triggered by the effect of moisture.

Organic oxygen scavenger/indicator

Methods and apparatus for characterising OSI-materials provide for: introducing the material into a measurement cell; subjecting the material to a gas mixture containing oxygen; permitting a certain time or at certain time interval or intervals to elapse; measuring a defined volume part of the gas mixture with regard to its oxygen concentration using a measurement circuit, which together with the time component represents a characterisation of the OSI-material, wherein the OSI-material in the measurement cell is subjected to the gas mixture circulated in a closed reaction circuit, and the defined volume part is conveyed into a measurement circuit containing a gas, for the measurement of the oxygen concentration.
