X-Ray Diffraction (XRD) Basic Operation

[@TylerChittum]

Very informative. You really nailed the 80s instructional video vibe as well.

[@sagartatkare17]

Zachery neale you did a great video. One of the easy to understand on you tube about X-RD instrument.

[@yessir3145]

Great video! VERY informative. Thank you

[@shreyamandal2711]

thank you, it was very useful demonstration.

[@evaristeu]

Very informative. Thank you very much

[@JellyDoing]

Wow Very cool Thanks for sharing

[@maherasad3128]

A perfect and helpful video

[@bcauchy]

Great video! I will take the XRD experiment. This video is very useful.

VERY EDUCATIVE

Well demonstration done❤

Are the goniometer circle radius and focusing circle radius same? If the material is fixed, how the radius is affecting the intensity of a signal? Can the goniometer radius be adjusted for an instrument?

[@ZGNeale]

On this instrument the X-ray source is stationary and both the sample stage and detector can change angle, which is theta and 2-theta. Other instrument setups can have a moving x-ray source and stationary sample stage. I think this instrument can also be setup for different scans, such as a rocking-curve scan, but I have never tried. At low angles the x-ray beam cross-section will be more distorted than at higher angles. This can influence intensity and noise. I suspect it would lead to broader peaks at lower angles because of the larger spot size, but you should double check a reference.

How much sample is used?

[@kuntalmondal4975]

Wow great

[@dipalichaudhary7556]

Very informative video. Is it safe to work on XRD instrument? Is analyst exposed to Xray radiations?

[@ZGNeale]

It is safe. The user is protected from X-Rays. The glass is made out of lead oxide which absorbs X-rays. And the machine automatically stops X-rays if the door is open.

[@dipalichaudhary7556]

@@ZGNeale Thanks for swift response, really appreciated.

[@badllama9194]

What song was used in this video. I liked it.

[@sudhaunshusp]

At the end of the experiment, please explain why would a need arise to contact technician if the alarm red light is on ? What is the hazard in that ?

[@ZGNeale]

This machine will not operate with the alarm light on. The user being trained in this video most likely does not have the experience to diagnose the problem. The lab technician in charge of the equipment should be contacted to fix the problem. If they are unable to resolve the issue, then the manufacturer will have to be contacted for service.

[@sudhaunshusp]

@@ZGNeale Thanks for your explanation.

[@jianzhao5799]

Pretty useful

[@Alan-y4u]

Excuse me what is this instrument configuration ? and Characteristic radiation?

[@ZGNeale]

This is in Bragg-Brentano geometry. The x-ray source is stationary and the sample holder and detector rotate at theta and 2-theta. It is using Cu-K radiation source.

[@badramrajusitharamarao1288]

Thanku sir,Please explain xrf for cement lab

[@abdulrahmanibrahimali8471]

What are the cost of such machine?

[@ZGNeale]

I am not certain, but I'd estimate anywhere from $50k for refurbished machines to $500k for new models with additional features.

[@phandinhthanh2295]

Well, so what is the sample made of ?

[@ZGNeale]

The material shown was an Al2O3 standard used for calibrating the equipment.
