Analysis of Air Filters by EDXRF

X-ray fluorescence is the preferred method to analyze samples related to air monitoring due to the non-destructive nature of the technique and the superior sensitivity achievable. In this application note it is shown that the Thermo Scientific ARL QUANT’X Energy Dispersive X-ray Fluorescence (EDXRF) instrumentation is ideal for determining concentrations of multiple elements on ambient air filters. The bench top instrument is capable of analyzing the elements sodium to uranium with minimal sample preparation.
