摘　　要：大气气溶胶水溶性离子自动监测仪为大气研究提供了一种全新的,在线监测大气污染及研究的手段,美国、欧盟已对国外的此类设备提供了测试报告或研制了相应的标准物质,我国目前在这一领域尚无质量控制技术。初步搭建了一种大气气溶胶水溶性离子自动监测仪校准装置,装置包括三个模块:气溶胶发生系统、采样系统、基于HJ799和HJ800原理的自动测试系统。最终以该自动测试系统得到的数据为标准值,给出前端装置的修正值或修正系数。通过实验,分别对三个模块的性能进行了验证,均满足各自在校准装置中承担的功能作用,但由于系统比较复杂,应进一步考察影响装置各模块准确性的因素,提升各模块的效率,得到一套具有稳定特性的校准装置。This paper introduces a novel calibration device for automatic monitors of water-soluble ions in atmospheric aerosols,aiming to address the lack of quality control technology in this field in China.While the United States and European Union have already issued test reports or developed standard substances for similar foreign equipment,this research contributes to the local development.The calibration device comprises three modules:an aerosol generation system,a sampling system,and an automatic test system based on the principles of HJ799 and HJ800.The final calibration relies on data from the automatic test system to provide correction values or coefficients for the front-end device.The performance of each module has been experimentally validated,confirming their suitability for the intended calibration roles.Due to the system's complexity,further investigation into factors affecting each module’s accuracy is necessary to enhance efficiency and achieve a stable calibration setup.
