Dear all, I am a new member of this mailing list. My background is environmental engineer. At the moment I am conducting a research related to the crystalline iron oxide magnetite. One of the analyses that I have to do is the determination the unit cell dimension (lattice parameter) of the crystal from X-ray powder diffraction data. So far, for the XRD analysis I have mixed my sample with an internal standard. Because I am a beginner in the crystallography, I would like to hear opinions on two things:
- Is using an internal standard a good way of sample preparation for the determination of unit cell?. Can anybody give me an example of a good internal standard that can be used for XRD analysis?. - Can anybody give me a suggestion which free software can be used for the determination of unit cell parameter from XRD powder diffraction data (with internal standard)?. I have learned a little about FullProf but I don’t know whether this program can handle XRD data with internal standard or not. My knowledge about FullProf is very limited, therefore if some hints about this program are more than welcome. Is perhaps FullProf too complicated for me as a beginner?. Thanks a lot and best regards Gumelar Pritosiwi -- Gumelar Pritosiwi Institute of Environmental Technology and Energy Economics Hamburg University of Technology Eissendorfer Str. 40 21073 Hamburg Tel +49 40 42878 3319 Fax +49 40 42878 2315
