Accurate determination of components released from the VIP is crucial to the selection of the getter that is vital to maintaining its performance of insulation. In this paper, in observation of application of the VIP on marine reefer containers, the VIPs co-developed in our lab were undertaken gas chromatography-mass spectrometer tests to detect the pyrolysis gases released from VIPs at the working condition similar to that of marine reefer containers, and analysis of the composition of the getter was performed by employing the SEM and EDS. It shows that the composite, which was developed by incipient wetness impregnation of cupric nitrate solution on the activated carbon having a high specific surface area, performs well in adsorbing ethylene and propylene from pyrolyzed substances. It is also demonstrated that the as-prepared composite can limit the possibility of hardening of the getter from adsorption of the water vapor. Conclusions are drawn that the getter developed from activated carbon by loading catalytic metal is suitable for VIPs used on marine reefer containers.
