氮中二氧化硫气体标准物质称量不确定度的评估
|
摘要
环境中的二氧化硫需要不间断监测,二氧化硫仪器的定期校准离不开气体标准物质,用重量法制备气体标准物质称量不确定度的准确计算是气体标准物质量值准确的保证。
Sulfur dioxide in the environment needs continuous monitoring. The regular calibration of sulfur dioxide instruments can not be separated from gas standard materials. The accurate calculation of the uncertainty of the standard weight of gas materials prepared by weight method is an accurate guarantee of the quality of gas standard materials.
