Description:
Proton scattering analysis has been developed to provide light element analyses as a complementary method to x-ray analysis. Samples of air particulate matter from both filter and impaction devices have been analyzed and time sequence and particle size information obtained. In combination with x-ray analysis, total mass may be determined by summation of elemental masses; however, further investigation is needed to compare with the gravimetric method. Like x-ray analysis, it has a broad range, and is rapid, subject to automation, and non-destructive of the prepared sample. Analyses of typical atmospheric samples may be performed in five minutes or less. With further development, the method can readily be advanced from experimental to routine usage.
