Thanks for the instructions! I have some questions regarding this quantification method. When I tried all the step and click the default rievtveld fit (this is the setting in our xrd facility), it pops a message saying that "actual scan axis is not supported for refinement", and the sametime, I have noticed that all peaks in the peaklist are gone. I am not quite sure what this message means why this happens. Can I ask if you can help see where this error comes from? Thanks!
Thanks for your contribution. I have a few questions if you can help me. After matching all phases in a multiphase structure and adding CIF files, some peaks do not match after refinement. How can I fix this situation?
There are a number of reasons this could be. Maybe the refinement changed the lattice parameters too much, maybe the sample height displacement changed too much, maybe the sample has a lot of texture (causing the intensity fits to match poorly), etc. It is really difficult for me to say without seeing the refinement results (raw data vs. calculated pattern).
When I do convert pattern to phase, dont get anything. So when i go to the next step for refinement, i am not getting the tolerance tab to change the values. am i missing a step?
If you aren't getting any numbers appear next to your phases, then please watch this video: ruclips.net/video/yGQDXCXEaqY/видео.html. Let me know if this doesn't solve your problem. And if you are unable to solve the tolerance, you may just have an older version of HighScore Plus. I'm not sure how to do that in older versions, but I don't think it will matter much if you leave the tolerance value at the default.
Thank you very much for the tutorials. At the bottom, If I had put " Profile fitting" as the Desktop name, then " Fit a Profile " is not have been activated. I had put "Rietveld Analysis" as the Desktop name, then in " Fit a profile," is showing only three option " Clinker , Default & Stress-Strain Analysis".......Please help me
Default might work well for you, although I don't know if "Fit a Profile" applies only to peak profiles or phases. Without knowing what refinement steps are programmed into it, it is difficult to say for sure. I'm not sure if I know where "Fit a Profile" is located in the software (we may have different versions with different labels). However, if you want to make your own automatic refinement programs, you can follow the instructions in this video: ruclips.net/video/0fJ6RRWOhRU/видео.html. If you are unable to perform phase quantification, it could be that you do not have the required version of HighScore (I believe you need HighScore Plus, not just HighScore).
That is very difficult to answer without knowledge of the specific situation. If you want to email the diffraction pattern and some information about your sample (such as what phases/elements you think are present) to mkoehler@utk.edu, I can take a quick look at it when I have time to see if I can give you any advice regarding how to start improving your analysis.
That may be your issue then. From the looks of www.malvernpanalytical.com/en/assets/PANalyticals_HighScore_suite_brochure_tcm50-51981.pdf, it sounds like HighScore (without the Plus) doesn't do Rietveld, but I'm sure Malvern Panalytical could give you a more definitive answer and price the Plus option, if needed. I wish there was something else I could do to be of more help!
Sir, i have a question, how do you got that phase percentages i am trying in the same way you did but not able to get the percentages and what the term you mentioned "ctrl, not shift" exactly mean?
Are you able to refine the data? Are you getting any kind of error message when you try to perform a refinement? And what is the time at which I said "ctrl, not shift"?
Thank you for your excellent video, Michael Kaler. I have a few questions. I have analyzed my sample using Highscore Plus with Pdf2, and I want to perform phase quantification with Rietveld refinement. Do you have any suggestions for me to do quantitative phase analysis without buying pdf4 databases?
One option is to see if you can find a good .cif file on the Crystallography Open Database (COD). I don't know how reliable the data are from that database though as I've never used it. If you can find a good .cif file, you can go to File, Insert in HighScore Plus and insert the .cif file. It should then be inserted as a phase that you can refine. Another option is to find atomic position information in a journal article. You can then convert one of the PDF-2 patterns to a phase and manually add the atomic position information. If you do it this way and need help figuring out how to enter the atomic positions, let me know. Good luck!
I'm guessing you already have your refinement complete in HighScore. If so, go to the "Scan List" tab (in the same part of the window as "Pattern List" and "Refinement Control" tabs). You will probably only see one scan present, the one you are refining. If you right click on that scan, you should hopefully see an option like "Convert calculated Profile to Scan." If you click that, it will make your calculated profile (the refinement curve) a separate scan. If you double click the new scan that appears, you should only see your refined/calculated pattern on the screen (the raw data disappear). You can then go to File, Save As, and save it as an XRDML file. You can then either find that new XRDML file on your computer, right click, and choose convert (that works on my computer), or you can open it in Data Viewer, click on File, Convert, and then choose .csv or .xy. One of those should work for you. I'm not positive they can be opened in Origin, but I know they can be opened by Excel, and then you can copy the data to Origin. Please let me know if this works for you.
@@IAMMDiffractionFacility Hi..I tried but I am not able to see only refined/calculated pattern .Can you make a tutorial of the steps leading up to saving of the file.it..as I have to make my final pattern in origin. Thank you for all your videos,they are very helpful.
Thank you very much for all these tutorials. Trust me, these are really helpful. I have a question- Does the percentage of MnO2 and quartz indicate weight fraction or volume fraction? I would be really grateful if you could kindly share your opinion. Thank you so much again for all your time and efforts.
@@IAMMDiffractionFacility Thank you so much. I have been immensely helped by your videos. Would you mind sharing your email? I am doing my graduate studies here at UCF.
Very nice! I actually grew up in Florida (well, for my first 12 years or so of life), only about 2.5 hours from UCF. I was going to say how lucky you are to be so near all of the theme parks, but I'm guessing none of them are open now :/ My email is mkoehler@utk.edu.

Thank you. Sir any about ideas for sum of net intensity value getting in sacn statitisc. How to this value calculated.
May I ask why you want net intensity? And do you mean the intensity of each individual peak or the intensity of each individual data point?

I’ll try as your nice suggestions.
where can I get this highscore software..
You can contact Malvern Panalytical to get a price quote.
Thank you for your endeavour.
