Powder X-ray Diffraction (XRD)

Equipment

The department has 2 Bruker XRD's and a Philips XRD providing powder diffraction analysis.

There is an ICDD PDF2 database for indexing patterns with EVA® and access to Topas® for refinement.

External users can access this software for data processing

The Bruker D8 is equipped with a LynxEye detector and a 90 position auto sampler.

  • It is configured in vertical theta/2theta Bragg-Brentano and has a scanning range of 2-150°
  • It has the capability to use different radiation sources (Cu Kα and Co Kα)
  • The instrument can run samples on either reflection or capillary stages

Measurement capabilities are:

  • Qualitative phase analysis
  • Quantitative phase analysis
  • Structure solution and refinement
  • Crystallite size determination  

The Bruker D8 Advance is equipped with a Vantec detector, a 9 position auto sampler and a anton paar TTK-450 temperature control stage:

  • It is configured in vertical theta/2theta Bragg-Brentano and has a scanning range of 2-168°
  • It has Cu Kα source
  • The Vantec detector has an active area of 50 x 16 mm, covering > 12° (2Θ) with a very low noise level below 0.01 cps
  • Temperature range of TTK 450 chamber is from -193 °C to +450 °C in vacuum and -120°C to +300°C in inert gas. 

Measurement capabilities are:

  • Qualitative phase analysis
  • Quantitative phase analysis
  • Structure solution and refinement
  • Crystallite size determination
  • Temperature control experiments

The Philips PW1050 uses a Cu Kα source and is fitted with a secondary graphite monochromator.

  • The Philips has a scanning range of 3-105°

Measurement capabilities are:

  • Qualitative phase analysis
  • Quantitative clay analysis using the RIR (relative internal ratio) method

The Olympus Innovex X-5000 portable XRF is available for fieldwork and 

  • has a Rh source
  • capable of analysing powder or solid samples
  • fast analysis times - eg. 3 minutes.
