X-ray fluorescence analysis of ACHEX aerosols
The method of X-ray-induced X-ray fluorescence analysis (XRFA) used to determine the elemental compositions of aerosols collected on filter media and impactor films during the Aerosol Characterization Experiment (ACHEX) is discussed. The method involves the interaction of photons provided by an X-ray tube either directly or indirectly, with specimen atoms. The technique is quantitative, relatively rapid (minutes), and highly sensitive (ng/cu m of air). With low-power X-ray tubes (less than 40 W) and semiconductor detector X-ray spectrometers employed in the experiment, the concentrations of 13 elements (Al, Si, S, K, Ca, Ti, Mn, Fe, Ni, Zn, Br, Sr, and Pb) were routinely ascertained for aerosols collected over 2-hr periods.
