Particulate matter (PM) is one of the major contributors to air pollution. There is a need for simultaneous measurement of PM and its chemical properties to adjust processes parameters quickly and identify emission sources. The PX-375 simultaneously measures the mass concentration and elemental composition. The PX-375 relies on the beta ray attenuation and x-ray fluorescence techniques. A comparison with the manual analysis technique (ICP-MS) shows good correlation with field data collected.
