摘要
通过大量实验,以称量法制备氮气(空气)中一氧化碳、丙烷混合气体标准样品,以气相色谱法对其各项性能进行考核,确保汽车污染物检测仪器数据准确可靠。
Through a large number of experiments,the standard gas mixture sample of CO,C3H8/N2（Air） was made by weighing method. Then it was tested on its various performance by GC,which ensured the data of auto pollutants testing instruments to be accurate and reliable.
