| 摘 要： | 大气颗粒物采样器是《全面禁止核试验条约》(CTBT)中放射性核素监测的关键设备之一。结合实验室实际情况,成功研制了PMS-800大流量大气颗粒物采样器。PMS-800采用变频技术保持流量稳定,自动控制软件可实现采样过程的控制、数据采集和数据处理功能;用聚丙烯纤维滤材作为颗粒物的收集介质。对采样器的性能测试结果为:最大采样流量可达800 m3.h-1以上,流量不确定度小于5%;采样期间流量波动在±5%之内;当负载达到20 kPa时,实现停机保护;采样滤材对0.2μm气溶胶的收集效率为82.5%;自采样开始每10 min存储一次系统参数。该采样器满足CTBT相关技术文件的要求。
