| 摘要: |
| 以环境空气中挥发性有机物（VOCs）监测为例，比较分析了标准物质在应急监测、实验室定量分析，以及应急监测定量、半定量分析中的作用。结果表明，在有标准物质进行定量校准时，应急监测方法和实验室标准分析方法的定量结果具有可比性；在无标准物质进行半定量分析时，应急监测结果可能存在较大误差。提出，在需准确定量的应急监测中应使用标准物质进行校准，以保证监测结果的准确性。 |

| Abstract: |
| This study takes the monitoring of volatile organic compounds (VOCs) in the air as an example to compare and analyze the role of reference materials in emergency monitoring, laboratory quantitative analysis, and quantitative and semi-quantitative analysis of emergency monitoring .The results showed that the quantitative results of emergency monitoring and lab monitoring are comparable when the reference materials are used in quantitative calibration, while lager deviation may exist in the emergency monitoring by semi-quantitative analysis without the reference materials. It is proposed that standard materials should be used for calibration during emergency monitoring that requires accurate quantification to ensure the accuracy of the monitoring results. |
