Short summary

This study presents the deployment of the Xact® 625i Ambient Metals Monitor in Milan (Po Valley, Italy) and its performance in measuring particulate matter elemental composition at a high temporal resolution. Our findings demonstrate strong agreement between online and offline X-ray fluorescence analyses, underscoring the potential of advanced monitoring technologies for air quality research.
