  • An mBraun position sensitive detector (PSD) is used for rapid data collection

  • PSD acquires data for a 2-theta range of 10o at a resolution of 0.02o/channel

  • PSD is used for fast studies of reactions, kinetics, phase transformations, or crystallization

  • Rapid data collection software developed by HTML
XRD scans of potassium sulphate at 650oC (top) and 450oC (bottom). Each trace was acquired in only 15 seconds, with 30 seconds between the two temperature settings, for a total of only 1 minute of instrument time.
Bi-Sr-O HTXRD patterns taken rapidly using the PSD characterize the phase transformation in bismuth strontium oxide on heating between 627oC to 690oC.
