摘要

参考标准物质研制技术,采用称量法制备了一批瓶装氮中SO2和NO混合标准气体,对混合气体的适用性进行了验证,并通过实验室比对考察了混合气体在生态环境监测领域的应用情况。结果表明,研制的SO2和NO混合标准气体具有较好的适用性,可以使用混合气体开展实验室比对,并在实际生态环境监测领域实验室比对中取得了良好的应用效果。实验室比对结果显示,SO2和NO评价结果为满意的实验室比例分别为79.4%和81.4%,表明目前我国气体SO2和NO整体检测能力和技术水平良好。

Abstract

Referring to the reference materials development technology, a patch of cylinders of SO2 and NO standard gas mixture in nitrogen was prepared by gravimetric method, and verified for applicability.The application of the gas mixture in ecological environment monitoring was investigated by inter-laboratory comparison.The results showed that the standard gas mixture was suitable to carry out inter-laboratory comparison and a good application effect was obtained in practical ecological environment monitoring inter-laboratory comparison.The laboratory comparison results show that the proportion of laboratories with satisfactory evaluation results for SO2 and NO are 79.4% and 81.4%, respectively, indicating that the overall detection ability and technical level of SO2 and NO in China are good.
