Energy Dispersive Diffraction : Advantages

• Can see “inside” unconventional sample environments

  • Within limits: can have steel or other materials shielding the sample at pressure and/or temperature
    • thus samples can also be immersed in gas or liquid (hydrothermal synthesis)
    • in-situ studies - reactions / explosions / properties under stress. Particle flows within gases and fluids. Reactions in gas/fluid flow lines.
    • Only see diffraction in the volume (nick-named the “lozenge”) defined where the detector collimator subtends onto the incident white X-ray beam

• Spatial Resolution inside the sample environment

  • Can narrow down the beam and collimator - and move the sample : thus obtaining diffraction patterns from different spatial volumes inside the sample environment

• Fast data collection times

  • minutes to fractions of a second
