Measurement of trace metals in ambient air: Validation of a rapid technique with gold standard ICP-AES
Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects.
The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive.
The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection system enables near-real-time trace metal measurements in ambient air. Modifying the Xact monitor to also characterise metal concentrations on externally collected filters would greatly expedite the analysis process and reduce costs.
