Qualitative and quantitative phase analysis


D8 Focus diffractometer system Technical data:

  • geometry – Vertical Theta/2 Theta
  • measuring circle diameter – 435 mm
  • smallest step size (Theta/2 Theta) – 0.0001o
  • reproducibility (theta/2 Theta) - +- 0.0001o
  • maximum slew speed – 1500o/min
  • angular position – stepper motors with optical encoders
  • central opening of Theta ring – Ø 10 cm
  • angular range (Theta) – unlimited
  • angular range (2 Theta) - –110o to 168o

Theta/2 Theta base goniometer X-ray Generator Kristalloflex K785 Technical data:

  • maximum continuous power – 2,4 kW
  • high voltage – 20-60 kV, adjustable in steps of 1 kV
  • current – 5-60 mA, adjustable in steps of 1 mA
  • power required – 5.5. kVA (25 A max.)
  • stability - ≤ 0.005% for high voltage and current The generator needs to be connected to an external water supply for cooling purposes (inlet pressure of the water – 3-6 bar; temperature – 2-20oC).
