| Abstract: | The research progresses of the preparation technology for greenhouse gas standard materials were reviewed. The type and the uncertainty of green house gas standard materials were classified. The feasibility of different preparation technologies to meet demand of greenhouse gas monitoring was also studied. The comprehensive effects of dilution operation, the pretreatment of gas cylinder and the choice of pipeline materials on the stability of standard substance were discussed. The difference of the traceability system between BIPM and WMO was compared. |
