摘　　要：根据欧洲Ⅵ号标准,研制出低浓度汽车尾气监测用气体标准物质。该标准物质采用GB/T 5274—2008《气体分析校准用混合气体的制备称量法》中规定的方法制备并计算定值,采用气相色谱和氮氧化物分析仪对标准气体的均匀性和稳定性进行了考察,并对称量法制备过程的不确定度进行了分析评价。所制备的汽车尾气监测用气体标准物质与标准样品进行了比对,从而确保了所研制气体标准物质的量值准确可靠。This research report describe development of the gas reference materials for low concentration automobile exhaust detection, based on European standard VI. The gas reference materials is prepared with the provision methodology of GB/ T 5274--2008 ＂Preparation of Mixture Gas for Calibration Analysis Weighting Method＂, the uncertainty and uniformity is estimated by applying gas chromatography and nitrogen oxides analysis instruments, and the uncertainty is estimated by weighting method. The gas reference material is compared with sample, which ensures the accuracy and reliability of the standard material.
