Elemental analysis of soluble and insoluble fractions of rain and surface waters by particle-induced x-ray emission.

Abstract

H A procedure has been developed and tested for the analysis of small water samples, using particle-induced X-ray emission (PIXE) for soluble and insoluble elemental constituents separated by Nuclepore filtration. Nanogram sensitivity for samples in the 0.17-cm2 target area of a Van de Graaff accelerator proton beam permits the simultaneous determination of… (More)
