Abstract. We developed an automatic device able to sample and analyze in situ and in real time airborne particulate matter (PM) using the X-ray fluorescence of the chemical species layered on a filter, having atomic numbers between 19 (Potassium) and 82 (Lead). Furthermore, we developed a calibration technique, which gives the parameters for real time automatic determination of the absolute mass of the chemical species present on the sample, with a sensitivity varying from 1 to 100 μg per sample.

Our system could represent a simpler alternative to the complex and sophisticated laboratory measurements, such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES), officially used by environmental agencies. A 6 month in-situ test, carried out in collaboration with the local Regional Environmental Agency, showed that our system gives results comparable with the ones obtained using existing techniques, but with smaller errors. The methodology developed has been submitted for a patent.
