HJ836-2017测定废气中低浓度颗粒物的验证研究

Study on the validation of HJ 836-2017 for determination of low concentration particulate matterin exhaust gas

对《固定污染源废气低浓度颗粒物的测定重量法》(HJ 836-2017)的检出限、同步双样和实际样品进行测试验证。结果表明,检出限和同步双样的测试均满足方法标准的要求;实际样品经过比较测试后证明数据准确、可靠,可应用于"超低排放"企业的低浓度颗粒物监测。

The detection limit,synchronous double sample and actual sample of<Stationary source emissionDetermination of mass concentration of particulate matter at low concentration-Manual gravimetric method>(HJ836-2017)has been tested and verified.The results showed that both the detection limit and the synchronous double sample test meet the requirements of the method standard,and the actual samples are verified to be accurate and reliable after comparative tests.It can be applied to monitoring low concentration particulate matter in'ultra low emission'enterprises.
