Online monitoring of atmospheric heavy metals

The AOA 200 Atmospheric Heavy Metal Online Analyzer is a self-developed online atmospheric heavy metal continuous monitoring instrument that utilizes wave sound fusion X-ray fluorescence non-destructive testing technology, beta ray absorption detection technology, and automatic enrichment technology for air particulate matter. It complies with the US EPA IO-3.3 standard method. Not only can it monitor the mass concentration of air particulate matter, but it can also quantitatively analyze the elemental composition of particulate matter. It can achieve the monitoring of low levels of heavy metals such as lead, cadmium, chromium, arsenic in air particulate matter and the coordinated measurement of PM concentration, unmanned and long-term automatic monitoring.
