I am currently using a Siemens D500 Diffractometer to test metallic glasses for amorphocity. I have read in some papers that the sensitivity of the XRD is known, i.e. what percentage of the metal needs to be crystalline for the XRD to pick it up. Would anyone know where I would find information like this for the Siemens XRD I am using?

An example of the sensitivity I have found is that the structure needs to be at least 5% crystalline for the XRD to pick it up. Below that, no crystal structure can be found.

Cheers, any help would be greatly appreciated.
