| Abstract: | The accuracy of the value of the reference material is an important prerequisite for the accuracy of the monitoring data.In order to scientifically evaluate the accuracy of the property value of commercial gas reference materials of 57 ozone precursors,an analysis and comparison method of En value and gas chromatography equipped with loop,Deans Switch and double FID was established.Based on this method,the consensus of 6 brands of gas reference materials containing 57 ozone precursors (PAMHC) was evaluated.Among the 6 brands,4 brands showed good consensus and accuracy,2 brands showed a significant deviation in 5-22 compounds (absolute En value ranged 1.0 to 5.3).This result indicated it should pay more attention to the quality of PAMHC gas reference materials in ozone precursors monitoring. |
