Ordered/crystalline and semi-crystalline materials:

• Powders: 20 mg – 3 g
• Solids: < 35 mm (diam) x 7 mm (height)

The XRD instrument works by irradiating a sample with a beam of incident X-rays while the beam and detector move in a synchronized motion. The crystalline parts of the sample exhibit long-range order of repeating arrangements of atoms, molecules, or ions, diffracting the X-rays into many specific directions. The signal produced by the sample is recorded in a diffractogram displaying the scattered intensity as a function of the angle between the incident and the diffracted beam. This pattern reveals information related to the atomic structure of the sample

XRD provides information on atomic or molecular crystalline structure and phases. It can also be used to confirm if a sample is XRD amorphous.

Detection limits. XRD detection limit is usually in the range of 1-2% vol.
