Analysis Of Atmospheric Aerosols Collected In An Urban Area In Upstate Ny Using Proton Induced X-Ray Emission (Pixe) Spectroscopy, Jeremy Smith
Honors Theses
We have performed a PIXE analysis of atmospheric aerosol samples collected in Schenectady, NY, to study airborne pollution in an urban environment. The samples were collected using a PIXE International, 9-stage, cascade impactor that separates the airborne particles according to aerodynamic diameter and deposits them on thin Kapton foils. The impacted foils were bombarded with 2.2-MeV proton beams from the Union College 1.1-MV Pelletron accelerator and the emitted X-rays were detected with an Amptek silicon drift detector. The X-ray energy spectra were analyzed using GUPIX software to determine the elemental concentrations in the samples. A broad range of elements from …

Comparative Study Of Aerosols Using Particle Induced X-Ray Emission, Colin L. Gleason
Honors Theses
A comparative study of atmospheric aerosols was performed on samples collected in Schenectady, NY using Particle Induced X-ray Emission (PIXE) spectroscopy. PIXE is an elemental analysis technique used to measure the elemental concentration of a sample. This is part of a systematic study to identify the sources and understand the transport, transformation, and e˙ects of airborne pollutants and the connection between aerosols, the deposition of pollution, and the uptake of pollutants by wildlife and vegetation. The atmo-spheric aerosols were collected with a nine-stage cascade impactor that allows for the analysis of the particulate matter as a function of particle size. …
