Description

Qualitative and quantitative phase analysis, suitable for analysis of different samples in different conditions.

Specification

  • Configurations - vertical goniometer, Theta/2Theta or Theta/Theta geometry
  • Measuring circle diameter - predefined at 500 mm, 560 mm and 600 mm (depending on set-up) or any intermediate setting
  • Max. usable angular range –110° < 2Theta ≤ 168° (depending on accessories)
  • Angle positioning - stepper motors with optical encoders
  • Smallest addressable increment - 0.0001°
  • Instrument alignment - equal or better than ± 0.01° 2Theta; NIST SRM 1976a always included (at constant climate)
  • Maximum angular speed - 20°/s (depending on accessories)
  • Detectors - point detectors: 1-D detectors: LYNXEYE; all detectors guaranteed without defective/dead strips or areas
