Maxxam all-season passive sampling system (PASS) is introduced in this paper. The PASS can be used to quantitatively and accurately monitor SO2, NO2, O3, and H2S in air in all weather conditions with flexible exposure times from several hours to several months. The air pollution detection limits of PASS are very low. They can be from sub ppb to ppt levels. The principles of proper use of passive samplers in the field study are discussed by using the PASS as an example.
本文介绍了Maxxam全季节被动采样系统(PASS)。该PASS可用于在所有天气条件下对空气中的二氧化硫、二氧化氮、臭氧和硫化氢进行定量准确监测,暴露时间灵活,从数小时到数月不等。PASS的空气污染检测限非常低,可从亚ppb到ppt水平。以PASS为例,讨论了在实地研究中正确使用被动采样器的原则。
