固定污染源颗粒物监测中滤筒的质量控制

Quality control of filter cartridge in monitoring of particulate matter determination in the stationary source

文章探讨了颗粒物监测中滤筒称量的质量控制措施,从滤筒筛选、恒重处理以及标准滤筒制备等方面进行了阐述。明确标准滤筒制备方法,引入标准滤筒的恒重对采样后滤筒称量进行质量控制。分析了影响滤筒恒重的原因,指出环境湿度、称量时间会对称量结果产生影响。

The article discusses the quality control measures of filter cartridges in particulate matter determination,which includes pretreatment method and constant weight.Establish a standard filter cartridge preparation method,introducing the constant weight of the standard filter cartridge to control the process of the filter cartridge after sampling.The reasons that affect the weighing of the filter cartridge are analyzed,and it is pointed out that the circumstance humidity and weighing time will affect the results.
