Analysis of Airborne Particles on Air Filters Using ICP–OES

Air pollution is of continual concern to industries, governments, and populations worldwide. Monitoring and analysis of the elements present in airborne particles have become the responsibility of many organizations in industry, government, and private research laboratories. Fortunately, modern laboratory-grade spectrometric analyzers are available that can handle these analyses.

This paper focuses on airborne particle analysis technology carried out on a discontinuous basis, sample by sample, via laboratory-grade ICP-OES.  For the trace analysis of toxic heavy metals, ICP-OES is an established analytical method and accordingly, several standard methods describing the usage of inductively coupled plasma optical emission spectrometry (ICP-OES) exist for the analysis of airborne particles, like EPA IO-3.4 [7] or EN 14385 [8].

For the analyses reported in this paper, all measurements were performed with the SPECTROBLUE ICP optical emission spectrometer with twin interface plasma observation, which enables the automatic axial and radial observation of the plasma with every measurement.
