Séminaire du Pr. Elzbieta Stefaniak

Catholic University of Lublin, Department of Chemistry, Poland
Analysis of inorganic particulates by means of the integrated microanalytical techniques
SEM-EDX and Raman microspectrometry

Scanning Electron Microscopy (SEM) equipped with a energy dispersive X-ray detection (EDX) and Raman microspectrometry have been recognized as useful techniques for studying a structure of matter, both large complex objects (works of art, composite biomaterials, minerals and ores, etc) and small particulates of different origin. Some possibilities of parallel application of the two microprobes to characterize inorganic micron-size particles are presented. There are basically two strategies involved: the first one is based on the automatic analysis of a large particle population, followed by clustering verified by Raman microspectrometry. The other one is based on the selection of specific, individual particles by SEM/EDX, followed by their relocation and analysis by Raman microspectrometry. Some analytical capabilities of a hybrid, 2-in-1 instrument, will also be demonstrated.

Le séminaire aura lieu le 12.12.2012 à 10h30
