Scanning Proton Microprobe Microanalysis for the Investigation of Homogeneity of IAEA Urban Dust Reference Materials
Journal of Radioanalytical and Nuclear Chemistry(2000)
Abstract
In order to develop new reference materials for microanalytical nuclear techniques, the Scanning Proton Microprobe (SPM) technique was used to determine homogeneity levels within 100×200 μm 2 micro-area on small pieces of IAEA Urban Dust reference materials. The experimental methods are described in detail. The results show that IAEA-396A/M Vienna Urban Dust is homogeneous enough for a SRM (≤10% for Si, S, K, Ca, Fe, Cu, Zn) for small sample analysis.
