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

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.
