The “A-Unit” is a D5005 base goniometer set up in θ-2θ mode and optimised for high quality powder data collection. It is fitted with a focusing primary monochromator and 2.5° Soller slits, giving well collimated monchromatic radiation. It is thus especially suitable for the collection of data for structure solution and/or Rietveld refinement, and for long d-spacing materials. Due to the tight and symmetrical line-shape characteristics of the instrument, it is also well suited for the investigation of strain and crystallite size effects.
Instrument specifications:
- Bragg-Brentano geometry
- θ–2θ operating mode
- Data collection from 0.5 to 140° 2θ
- Quartz primary monochromator
- Cu Kα1 radiation
- 2.5° primary and secondary Soller slits
- Scintillation detector
- Rotating single sample holder with user selectable rotation speeds
Well suited for:
- Collection of data for structure solution and/or Rietveld refinement
Not so good for:
- Samples containing fluorescing elements (Fe, Co, Mn), depending on the concentration.
