From: Beryllium Detection in Human Lung Tissue using Electron Probe X-Ray Microanalysis
Beryllium grid mounted on an aluminum stub. First panel, top row: secondary electron image. Second panel: background (bremsstrahlung) X-ray spectrum. Third panel: X-ray map for beryllium. Fourth panel: X-ray map for aluminum. First panel, bottom row: X-ray map for carbon, showing some contamination with organics. Second panel: X-ray map for sulfur. Third panel: EDXA spectrum from grid, showing peaks for beryllium, carbon, and oxygen (left to right). Fourth panel: EDXA spectrum from hole in grid, showing peak for aluminum.
