The D8 Focus is designed to be a high throughput instrument and takes the role as a lab workhorse, with the capacity to collect tens of datasets per day: On well crystallised samples it is possible to assess sample purity with a scan of just a few minutes and to perform quantitative Rietveld analysis on data collected for less than an hour.

Instrument specifications
  • Bragg-Brentano geometry
  • θ–2θ operating mode
  • Cu Kα radiation
  • 9 position sample changer
  • 2.5° primary and secondary Soller slits
  • LynxEye™ SuperSpeed Detector
Well suited for:
  • Booking system - useful if you wish to measure your samples straight after production etc.
Not so good for:
  • Samples containing cobalt (due to fluorescence). Then the Da Vinci 1 is recommended since its detector has better energy discrimination.
