Proton Non-Rutherford Backscattering Spectrometry for Measuring Hydrogen, Carbon, Nitrogen and Oxygen Concentrations of Aerosol Collected on Nuclepore Film

Particle induced X-ray emission(PIXE) analysis of aerosol samples for measuring concentrations of elements with Z＞12 is one of major applications at the GIC4117 Tandetron at Beijing Normal University. In order to measure H, C, N and O concentrations in aerosol samples, proton non-Rutherford backscattering spectrometry (PNBS) was employed with an Au(Si) surface barrier detector at an angle of 160° in PIXE chamber. PNBS spectra of 4 aerosol samples collected on nuclepore filters were fitted with SIMNRA. H and Si concentrations are comparable with those of proton elastic scattering analysis(PESA) and PIXE, which indicates that PNBS can be used for the analysis of aerosol samples collected on nuclepore filters.
