How to use X'pert highscore plus for Rietveld refinement of XRD pattern?
You can use FULLPROF. Manual and various tutorials are available on internet.
For information regarding the use of high score plus for rietveld refinement, website of PANALYTICAL or website of universities/institutes (like MIT) containing manuals and tutorials can be helpful.
As S. Abbas has said already, the website set up and maintained by my colleague Dr. Scott Speakman at MIT includes useful guides and tutorials for XRD and also for HighScore Plus. The tutorials page can be found here: .
I have some problem for Rietveld refinement by X'pert perogram!
I think that my results not match..? please explain Rietveld refinement by X'pert...
Hamid - Rietveld refinement by HighScore Plus is essentially the same as Rietveld refinement by GSAS, Jade, FullProf, Topas, etc. Your question is too vague to provide you any sort of useful answer, except that it appears from your question that you require a fairly basic understanding of the method.
For the program - Try running the tutorials that are included with HighScore Plus. The "Help" directory is extremely well documented, and is an excellent resource.
For the method itself - I highly recommend the book "Fundamentals of Powder Diffraction and Structural Characterization of Materials" by Pecharsky and Zavalij. It can be purchased online at a very reasonable cost.
Use these:

Hello,
I have a question about X'pert highscore. I am trying to make search /match first of all, I couldn't find my composition in the list. I read all the manuals. What I see is that, there is only 14 pattern listed in the pattern list windows (on the right). Is that means there is no library loaded ( ICCD for instance ) ?
Murat - that is correct. HighScore ships with a default database with only a small number of patterns - enough to do all the tutorials listed in the Help directory.
For more serious work you need to install a larger database. The "gold standard" is the PDF-4 licensed from the ICDD, which is rigorously reviewed and updated annually. The ICSD is also pretty good. A free database you can download and use is the Crystallographic Online Database (COD) from www.crystallography.net
Does anybody know how to delet peaks from the scan that I know are from the sample holder and not my sample, and not have the intensities to be negative and cause problems when trying to run Rietveld refinement in Highscore Plus? Thanks
Thanks Elisban. I was indeed subtracting the background before doing the Rietveld refinement. That might be the problem. I was also wondering if you know anything about deleting peaks from the scan. If I just click delete peak, it disapears from the peak list but still shows up on the graph. However, when I tried to 'delete from scan', that's when I got my graph weird and showing all the intensities negative.
@Mr. Elisban Sacari
I have different situation, I intend to insert some peaks and do peak profile, however a msg occur "negative intensities in scan data points". Anyone know how to overcome this issue?
*I also tried to do the peak profile before/after subtract background and/or smoothing. It seems these negative intensities comes from my raw data. pls help.
Can anyone advise on how to use quantification icon or quantify a mineral in x'pert high score plus v.2.0 ?
@Firman Magasa
One thing you can do to overcome "negative intensities in scan data points" is to select your scan, go to the object inspector and look for "Shifts". There is an option there ("Add [cts]") where you can add counts to your scan until it is all positive.
can anyone have the
PANalytical X'Pert HighScore Plus software? please shear it,
@Aruna Devi - PANalytical HighScore Plus is commercial software. It can be licensed from PANalytical. If you are looking for free Rietveld software you might try GSAS, FullProf, or Rietan.
Yon can use the video given in link below

i have PANanalytical HighScore Plus software in my lab. Any can tell me how to get PDF-2 / PDF-4 database free and how to add in HighScore Plus software.
How to find elements or compounds presents in XRD peaks using Xpert High Score plus software ?
Aruna Devi - the only way to get PDF-2/PDF-4 database for free is through software piracy, which is both illegal and unethical. These databases can legally be licensed from the International Center for Diffraction Data (www.icdd.com).
If you need a free database you can consider the Crystallography Open Database at http://crystallography.net. They offer a free database already formatted for PANalytical HighScore Plus which you can download here:
http://www.crystallography.net/cod/archives/2016/PANalytical/
How to add it is detailed in HSP help.
Nagaraj Shanbhog - XRD gives you structural information, so if you want composition (i.e., elements) you need to look at other techniques such as XRF or EDS. However, if you know the structure of the phase responsible for the peaks, you may be able to extract elemental information from the relative intensity of the peaks - this typically requires careful fitting of a structure model to the experimental data (e.g., the Rietveld method).
If by compounds you mean crystalline phases, then XRD enables this by comparing your data to a database of structures and running a search-match routine to determine the most likely matches. The links I just posted for Aruna Devi might be useful to you in this regard.
Edward Andrew Payzant: Your comments are really helpful, thank you very much.
Dear Edward Andrew Payzant, thanks for share your knowledge.
I would like to know more about the error calculus for the lattice parameter measure by using high score plus, could you help me? Thanks!
