摘要
简述了我国现阶段大气固定污染源颗粒物监测中遇到的问题及低浓度颗粒物采样与分析技术研究的必要性,归纳了国外低浓度颗粒物采样分析技术要点,包括大体积采样、滤筒上游采样设备堆积颗粒物的回收、有效称重步骤的确立等,并对我国开展低浓度颗粒物采样及分析技术研究提出了相关建议。
The issue was quite concerned about the particulate matters monitoring of stationary sources at the present stage in China. The necessity was described to research sampling and analysis technology of particulate matter at low concentration. The relative suggestions were proposed for the research about sampling and analysis of particulate matters at low concentration according to key sampling and analysis technologies of foreign countries such as high-volume sampling, recovery of deposits upstream of the filter and validated weighing procedure.
