Short summary
This study evaluates the performance of energy-dispersive X-ray fluorescence (ED-XRF) on particulate matter (PM10) samples collected on quartz and Teflon filters through an inter-laboratory comparison. Detection limits were higher on quartz, but measurement repeatability was similar. Strong elemental correlations suggest that, with proper corrections, quartz filters can provide reliable results. These findings support their feasibility for ED-XRF analysis.
