XRD lab
X-Ray System Configuration Malvern Panalytical X'Pert MPD PW3040
- XRD system specialized on polycrystalline samples, powder samples and nanoparticles
- wide range scans (2θ) for phase analysis
- 0.001° goniometer resolution
- Rocking curves (ω) used to quantify grain size and mosaic spread in crystalline materials
- X-ray reflectivity (XRR) for determining thickness, roughness, and density of thin films (<200nm)
- Anode: Cu: non-monochromatized X-rays, with a weighted average wavelength of 0.15418 nm
- Incident beam optics: Programmable Divergence Slit with beam attenuator, Mirror for parallel beam
- Sample stages: Bracket, Spinner (for powder), Capillary Spinner (for particles in solution), IR-Stage (for thin films)
- Diffracted beam optics: PRS/PASS & curved monochromator, parallel plate collimator (& flat monochromator)
- Detectors: Panalytical X'Celerator (high speed, high accuracy), large area proportional counter (for parallel beam optics, XRR)
