Hello,

    I am working with samples that contain an unknown amorphous phase, which I would like to quantify.  Does anyone know of any publications that might discuss some methods or techniques that may be used to determine the unknown amorphous phase. I would like to try and use a method that introduces an internal standard but I am open to all ideas.

Thanks,

You can find an example of this in  the most recent version of the DBWS distribution package (98007b) at:

You will see that the "scheme" is to have a digitized pattern of an amorphous material (presumably similar to yours, but also could be a pattern you collected of the amorphous material, IF you happen to have some on hand)   and then to refine the  scale factor for that pattern along with parameters of the crystalline materials you have in your model.

Good luck and please let me know how it goes for you .
Sincerely,
