    An other excellent video! Thanks for sharing them. They were a life saver when I had to give a lab lecture during lock down this past spring on precisely how to use this instrument and analyze the data.

      Haha, I didn't even think about lockdown making them more useful! And I really do appreciate the kind words. If ever you think of a video that would be helpful, feel free to suggest it. You can leave it in a comment or email me at mkoehler@utk.edu. I have some more videos almost finished that will be posted in the next week or so, but I'm always trying to figure out more that could help people.

    Thank you so much for your excellent videos for the instrument, sample preparation, and analyzing the data. They saved me a lot during my work on XRD empyrean PANalytical model. Looking forward to more videos on XRD. Happy to see such a simple and informative content, as I have looked for too long.

      Thank you so much for the kind words, they really mean a lot to me! I am very glad that these videos could help. I am working on some more crystallite size and microstrain videos that detail how to use Scherrer's equation and Williamson Hall plots. I'm also working on more videos similar to the Empyrean training video but that highlight how to set up samples with different sample stages.
      If you think of any videos that may help you, please feel free to suggest them. I'm always looking for more ideas. I can't guarantee that I can make whatever you may suggest, but I will certainly look into it.

      I appreciate the kind words! I have some hardware videos that I am working on right now regarding our XRF instrument, but I would like to get back to software videos. I have recently received new instruments, am awaiting installation of an upgrade to our Empyrean to allow us to perform pair distribution function (PDF) experiments, and have just been generally busy helping users. It has been a very busy time, which makes it difficult to find time to make more videos. Nice comments like yours encourage me to find the time though!

    Thanks for such a wonderful video. Can you please make videos on how to perform x ray reflectivity and xray reciprocal space mapping using same panalytical set up (prefix module for thin film) ???

    • @IAMMDiffractionFacility
      @IAMMDiffractionFacility  Год назад

      You have good timing, I am actually editing an X-ray reflectivity (XRR) video right now. I still need to record and edit video for analyzing the data, but I hope to have the video covering how to collect the data posted in the next week or so.
      The XRR data collection video utilizes the parabolic mirror and parallel plate collimator prefix modules with a Xe proportional detector on the X'Pert3 MRD from Malvern Panalytical (these same prefix modules are available on the Empyrean). Reciprocal space mapping (RSM) is on my list to get to at some point, but that may take me awhile since I'm also currently working on videos for pair distribution function (PDF) experiments.

    Thanks for the excellent training video. I have a quick question to ask. Can I start from 2theta = 3 degree? because some organic framework might give peak near 4 degree. Thank you

    • @IAMMDiffractionFacility
      @IAMMDiffractionFacility  2 года назад +2

      That's tough. If you are using the Pixcel detector, you start to get pretty high background (I'm guessing from the direct beam) starting somewhere around 4 degrees. As you decrease 2theta, the intensity increases VERY quickly. I believe that a smaller divergence slit would help, but you can also either use the detector in 0D mode or decrease the length of the 1D detector (this is done in the Detector tab in the Diffracted Beam Optics window). I would also suggest looking up information about a beam knife in the help files (these can be found under the Help toolbar in Data Collector). If you have one of those, I think it will help.
      Honestly, most of what I work on doesn't involve such small angles, so take my advice as simply suggestions of what you should look into.

    i want to know how to grease the goniometer of xpert pro PANalytical xrd machine or how to overhaul the goniometer. if any body knows please share..

      Unfortunately, I have never done this. I leave it to the Malvern Panalytical service engineers when they perform the preventative maintenance.

    HOW TO DO XRD OF THIN FILM SAMPLE?

    • @IAMMDiffractionFacility
      @IAMMDiffractionFacility  3 года назад

      Thin film samples typically utilize grazing incidence XRD, which uses parallel beam optics (although some films work fine with regular powder diffraction or a slight variation). Do you have a parallel beam mirror (also known as a parabolic mirror) and a parallel plate collimator?

      Ah, that's what I was afraid you meant. That sounds more like a question for an electrician. I couldn't even guess as to why your power/electricity would be fluctuating. I'm sorry I can't give you a good answer!
