If you don't have X-ray spectroscopy your SEM just isn't complete. In this module I cover X-ray analysis and mass spectometery. For the laboratory activity I just have them run and X-ray analysis on a variety of metal samples. For the lecture portion I describe the operation of the energy dispersive X-ray detector (EDS sometimes called EDX) and the wavelength dispersive X-ray Detectro (WDS). I want them to no about the pile up rejector and how it gives rise to dead time. The trade off between accumulation time, resolution and dead time. I also want them to know why WDS might be preferred over EDS and how thermionic vs. field emission influences the x-ray counts. I can show them how to do an elemental map and identify the different types of atoms/elements in the sample.

For the next part I do a survey of spectroscopy and spectometry. I am probably spending too much time on this but there is such a variety of surface analysis equipment out there that it is hard to included it all. Some that I consider important are Mass Spec, ICP-MS, SIMS, FIB, Atom Probe Microscopy, FTIR, Raman. I also briefly cover XPS. I am saving allowed electron transitions in X-ray generation for a later section. I will also cover XRD later. I want to finish up with the tools for now and move on to Nanomaterials which is a nice change and keeps the students interested.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
