铝箔复合膜气袋对温室气体吸附性的试验研究

Experimental study on the absorbability of greenhouse gases by gas-bags made of Aluminum foil composite film

摘要: 为了解气袋对温室气体气样的吸附性，采用气相色谱仪对5 L气袋中CH₄、SF₆、CO₂、和N₂O标准气体浓度进行了连续监测。结果表明，CH₄、SF₆、CO₂和N₂O气体浓度的变异系数分别为6.72%，0.95%，3.86%和6.56%，气袋对4种温室气体的吸附性均不显著，该气袋用于以上温室气体的测定是可行的。

Abstract: CH₄、SF₆、CO₂ and N₂O concentrations in 5 L gas-bag (Dalian China) were monitored using gas chromatograph (GC) to identify the absorbability of greenhouse gases by gas-bags. Results showed that Coefficient of Variation (CV) of CH₄, SF₆, CO₂ and N₂O concentrations during the experimental period were 6.72%, 0.95%, 3.86%, and 6.56%, respectively. No significant absorbability was observed, such bags are applicable in gas sample collection and storage.
