XRD Sample Preparation - Back Loaded Sample Holder - X-ray Diffraction

In this video, I will show you how to prepare a back-loaded sample using tools from Malvern Panalytical. This method is typically preferred as it helps reduce preferred orientation if the sample particles are not spherical, it produces a relatively smooth surface (smooth for a powder), and the sample height is better controlled. This sample holder is great if you want to perform Rietveld refinements on your data.

Thank you for explaing the procedure. It helps a lot

Do you know how much powder is needed for the Analysis (in grams)?

[MrPoorvank]

Helped me with my assignment. Thanks!!!!

Ok, and here we have best sample with a lot of preffered orientation. Any pressure on the back load the sample increase this effect :( ???

Hello sir. Thank you so much for this video. I have a quick question. I have sand (500micron) and clay(60micron) particle samples to run in XRD. I have been milling them in a ring &puck mill to try and get them at least below 45um / to a talcom powder consistency. I read that milling can cause damage to particles due to high heat so I have been adding Butanol to combat this (I read in papers). Also I read that particles can’t be below 1um, would this damage the sample result if they were ? As some of my clay sample had tiny amounts of particles below 1um, thank you :)

Hello, thank you for a video! I have a question. Is there a difference in results when I have a powder of fraction 100 micron and powder of fraction 200 micron? Or is there any specific requirements regarding to particle size of sample?

Thank you so much for the video 🧡 please i have a question ? Can we apply the XRD on cement powder ?? Like we just put cement without any adds ? Like how we can use the xrd in construction field ?? And thank you again

Hello👋 thanks for the video ❤ I have a question, what will happen if the powder is not properly filled in the sample holder? Does it make any difference on the XRD results?

Hi sir, if I just put an amount of powder that just exceeds a little and use straightforward the sample holder (to avoid pressing or rubbing too much the back surface of a powder sample), would it cause the upward sample displacement effect?

[m.mahimakumar]

If we use glass side directly on a sample leads to any preffered orientation?

[billytrinh]

How would I go about analyzing larger, solid specimens? Like say a 4" long x 1" wide stainless steel specimen

[cozyhobbies_]

Can I use a ring and pick mill for 10mins go grind my sample or will that cause phase transformation due to a lot of pressure ? Thanks

Is there any radiation effects daily worker as lab technician?

[michaeltapera]

I hear you said powder, can organic compounds samples be used in form of powder for taking XRD ?

[syazaninazurah]

Hello, can u give example of powder that we can used

[marasini]

I need your assistance regarding analyzing the data, can I get your email
