Abstract Platinum tetraiodide aerosols generated with a spinning disk from solutions in ethanol were used to test a particle size correction factor recently proposed by Criss for the X-ray fluorescence analysis of filter-deposited particulate samples. A set of standards of well-defined particle sizes in the range of 0.7 to 3.0 micrometers diameter was prepared by collection of these aerosols on Nuclepore filters. Measured Pt-L alpha and I-L alpha line sensitivities, plotted as a function of particle size, were in quite good agreement with curves predicted by the Criss equation. Problems and procedures in applying the correction factor to environmental samples are discussed.
