The effects of pressure on X-ray fluorescence analyses: pXRF under high altitude conditions

J. Anal. At. Spectrom., 2018, Advance Article DOI: 10.1039/C8JA00029H, PaperJavier Merrill, Victor Montenegro, Michael F. Gazley, Leandro Voisin As altitude increases, air density decreases, and the physics of X-rays being transmitted through air mean that the transmission of low-energy X-rays increases and accordingly the transmission effectiveness of low-atomic weight elements (e.g. Mg, Al, and Si) also increases. Here we assess the performance of pXRF units across a range of pressures. To cite this article before page numbers are assigned, use the DOI form of citation above.
