XRF Small Loose Powder Sample Preparation for Epsilon 1 from Malvern Panalytical
Hello dears, I am using XPERT high-score software to analyze the cement mix's XRD results. Although the major phases have emerged, I am having some issues. 1. Why do the main phases chosen from the pattern list not show up in the section on refinement control? 2. During double-clicking, one of the primary phases to view the details, there is no section on the structure and anisotropic displacement parameters. 3. Aside from these treatment options, how can I refine my graph to make it more readable? I would appreciate it in advance.
There are a couple of reasons I can think of quickly. 1) Do you have HighScore or HighScore Plus? I believe only the Plus variant has the capability to perform Rietveld refinements (but I'm not 100% sure of that). 2) If you are using HighScore Plus, it may be that your database of diffraction patterns doesn't include atomic positions. If this is the case, I THINK that the Crystallography Open Database (COD) has atomic positions in their files (or at least some of them), and it is a free database, so that might be something for you to look into. I've not used it personally as I use the PDF-5+ database from ICDD, but I've seen the COD recommended. Regarding making your graph more readable, that is a bit too broad of a question for me. Can you be more specific? Is there something in particular you want the graph to show?
Thank you very much for your high quality content and dedication. Really hope your channel will be seen by many more people. I got solo-access to a xrd about a year ago and since then I'm more or less teaching myself with literature and webinars (to be honest, the whole reciprocal space, symmetry and rietveld - thematics are very challenging, but "simple" measurements and phase qualification is getting better). My high-score software version is quite old (2.2) and the refinement controls aren't like in your tutorials, I guess the database is a bit outdated, too. Your content is incredibly helpful and your slightly longer introduction-video got me hooked. I'm very interested and looking forward to your next video - series, already ordered the book you recommended. Wish you and Benjamin all the best.
@WWC94 Wow, that message means a lot! I really never thought when I started this channel that it would have much reach outside of the users of my own lab, but knowing that it helps others has really encouraged me to keep it up and expand, even when the thought of expanding is a bit...intimidating. My intention was to produce only training videos on how to use our instruments. However, making videos focused more on the science behind X-ray diffraction has actually helped me as well. You don't REALLY know a topic until you try to teach it. As you said, stuff like reciprocal space, the details behind Rietveld...these types of topics can be difficult to grasp and then understand well. I'm not going to pretend that I'm a genius when it comes to X-ray theory; I'm better on the experimental side of things. I'm also not the kind of guy to understand a concept through equations, I need words and clear images to paint a picture to allow me to visualize what is going on. I figure that I'm not the only person like this though; there's probably a lot of people who are similar. My goal is to make content to help those people. Unfortunately, it is very time consuming to figure out how to simply a complex topic, which means this series will likely take much longer to complete than I anticipated. I hope that my viewers and subscribers will be patient with me! Anyway, this comment is longer than I intended. I just want to thank you again for your kind words. You didn't have to take the time to comment what you did, but it was very kind of you to do so. I hope you enjoy the rest of the channel's content, and let me know if you have any specific questions in the comment sections!
great explanation, really helps to understand how it works
Thank you, I'm so happy to hear that!
Hello! Nice video! So, how can I make a Vegard’s law XRD plot? What kind of software can make the quantification?
Thank you
You're welcome!
Excellent must continue
Thank you!
me, a graphic designer: ah yes, this is incredibly relevant to me
😂 That's a pretty crazy suggestion it sounds like RUclips made for you!
I am impatiently waiting for more videos...! Thanks
I appreciate that! The first one will release either in the next 24 hours or right after the weekend. Thankfully, I have a number of other presentations made, I just have to record and edit the audio.
Thank you for the wonderful effort you made on the expert score tutorial. I am using COD database compatible with Xpert highscore plus for Rietveld analysis. I continued with the tutorial until the step you change the phase asignments to pattern by CTRL+A and right clicking. After doing so, I did not find any numbers or phase names appearing on my graph.
@ahmadabubakar1364 To be honest, I am not overly familiar with the COD database as I have always used the ICDD database. I have two thoughts though. (1) Do you have HighScore or HighScore Plus? I believe you can only perform Rietveld refinements with HighScore Plus. (2) Maybe your candidate patterns that you tried converting to phases do not contain information regarding the atomic positions of each phase. If this is the case, you can't refine the phases based upon those candidate patterns. Please see this video for more detail (ruclips.net/video/yGQDXCXEaqY/видео.html).
I'm unable to fix the very low-intensity issues even during optimization (2 theta, omega, and Z). Can you please guide how to fix it?
Are you saying that your intensity while aligning is very low? If you perform a direct beam 2theta scan, what is your maximum intensity in cps?
how can we determine each peak is correspond to which planes???
If you have analysis software such as HighScore and a database of reference patterns, that is the easiest way. I have a phase identification video showing that. Once you identify the phases, you can find the peak list in the reference file, and that will tell you the (hkl) for each of the peaks. Otherwise, you need to index the peaks manually. I have a video for how to do that for a cubic system, but it gets more difficult as you move to lower symmetry systems.
@@IAMMDiffractionFacility Suppose I have the reference values of hkl for both phases... but their numbers are very close like SNO2 and Zno... How do I distinguish between them and what is the comparison mechanism? Do I compare the first two peaks in the references with the first one in the sample and the closest one is the correct one? Then compare two peaks in each reference and compare them with the second peak? And so on? I am facing a big difficulty in that. Can you help me?
More videos please...! please please
Hartmann Neck
Will You please provide me your email. I am facing some problems to fit some sample and I need your help
Thanks for video. How can I draw all the graphs obtained from HighScorePlus in OriginPro? Is there a way to get the data?
Perfect
Can you Please explain it for all no cubic
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).
Hi I'm following your guidelines but in my data, no candidates found appears. can you tell me its solution?
When you are on the chemistry tab selecting which elements to focus on, please look toward the bottom of the window. First make sure that the minimum number of elements is 1 and the maximum number of elements is something large (you can make it 100 if you like). Directly beneath that, you should see "Resulting hits: **** patterns of *****." Can you tell me what numbers yours shows? For example, in the video, it showed 1428 patterns of 412099.

can you share the excel template
Hi Michael, do you count with a configuration for capillary samples? If yes, what configuration and program are you using?
Hi. may i ask why my percentage does not appear?
hello, thank you for your explanation and video. For some samples, some people add internal standards in the powder. Why it is necessary?
How d= h2+k2+l2 i means is it any formula?
This is a really good video on XRD. Extemely underrated.
Thank you for this video , i find it very clear however i can not find the solver tolerance button in my Highscore Plus version ( 3.0d)
Why did you not include O and its atomic coordinates? What if I had 4e Wyckoff positions, should I enter 4 sets of coordinates? Thanks in advance!
Wait, I think I just answered my question. You said it was 0 oxidation. I still need an answer for the second question, though. Please.
Which can it be the best way to fill it with water solutions? In particular to avoid bubbles when you use a syringe.
This tube alignment method assumes that the incidence beam divergence slit and the detector's central pixel are almost perfectly aligned in one line with the goniometer's center. Are the correct and reproducable positions of the slit and detector guaranteed by manufacturer forever or they are adjusted by a user somehow before the tube alignment?
where i can find formula for calculating penetration depth? not in program, just formula, please
I am a postdoc. This was one of the best xrd lectures I’ve ever seen Great work
Thank you very much for the video. I'm a new user with Empyrean. Coudl you please explain why the omega changes with different samples (at 4'30'')?
Are these sample holders specific to the device used? For e.g we have rigaku Smartlab. I am not sure if it would be compatible with this
My apologies, but I'm also not sure as I have not used a Smartlab.
Thank you very much
Thank you for sharing this helpful video. I appreciate your time and effort.
Hello sir.. My sample is BaZrS3 I am not able to find this in the list what should I do then?
