NAC standard

2014-03-03 Thread Łukasz Kruszewski
Dear friends! I have a question regarding the NAC transmission diffraction standard, which is Na2Ca3Al2F14. Is this standard safe in use, i.e., do I need any special safety when grinding it? Best regards! -- Łukasz Kruszewski, Ph.D., adjunct Polish Academy of Sciences Institute of Geological

Hello all - I've gotten stuck at a point in my data refinement, I'd appreciate it if someone has any suggestions for me. I have been trying to index high pressure data. It was collected using a diamond anvil cell with a 2d detector. I integrated the data on GSAS II, using the penetration

Hi, I really enjoy your arguing ... The cell got by Topas is correct and the other programs fail to support this idea. Try ITO ... if you have at least 20 peaks. Back to real life where gems do not rule. To check a cell I can only recommend a standalone program nicknamed LePage, which is

Cell conversion may be done with the programs provided by Bilbao Crystallography Server (http://www.cryst.ehu.es/). Consider using the programs: GENPOS and CELLTRAN. On 03/03/2014 05:55 PM, Young, Lindsay wrote: Hello all - I've gotten stuck at a point in my data refinement, I'd appreciate
