摘要

介绍了气瓶装二氧化碳中全氟异丁腈(C4F7N)气体标准物质的研制过程。标准混合气是通过将全氟异丁腈和二氧化碳充装到铝合金气瓶中制备而成,采用称量法定值。对原料气体中杂质的进行了测量,综合采用经典稳定性评估和同步稳定性评估对该气体标准物质的长期稳定性进行了研究。结果显示该气体标准物质在6个月内的稳定性良好。该标准物质在(1%~30%)mol/mol的特性量值范围内,浓度的相对扩展不确定度为0.5％(k=2)。

Abstract

Research on gas reference material of C4F7N in carbon dioxide was reported. The gas mixture was prepared by filling pure C4F7N and carbon dioxide into cylinder. The certified value was from gravimetric method. The impurities in parent gas were determined. The long-term stability of this reference material was evaluated by both classical stability study and isochronous stability study. Results showed it had good stability in six month. The relative expanded uncertainty is 0.5% (k=2) for the mole fraction from 1% mol/mol to 30% mol/mol.
