Bruker D8 DISCOVER (2022)

The diffractometer and software are optimized for X-ray powder diffraction (XRPD). The diffractometer emits Cu Kα radiation with an X-ray generator that operates at 40 mA and 40 kV. Samples may be heated (up to 1200 °C in air, vacuum or inert gases). A monochromator can be attached for Cu Kα₁ radiation. The high energy resolution detector is ideal for removing fluorescence (e.g. from samples containing Fe, Mn, Co, etc.).

Main components:

• Cu Kα radiation
• LYNXEYE XE-T detector
• AUTO-CHANGER (can load up to 30 samples)

Options

• motorized divergence slits (default optics λ_CuKα1 = 1.5406 Å and λ_CuKα2 = 1.5444 Å)
• Johansson Monochromator for Cu Kα1 radiation (λ_CuKα1 = 1.5406 Å)
• Göbel mirror for parallel beam
• Anton-Paar HTK 1200N Chamber (RT – 1200 °C in air, vacuum or inert gases)
• Anton-Paar XRK 900 (RT – 900 °C in air, vacuum, inert gases or CO₂)
• Bruker TC-TRANSMISSION (only for capillaries RT – 900 °C in air)

Sample holders

• zero-background silicon plate holders (defualt)
• PMMA well holders
• back-loaded well holders
• capillaries
• Kapton film holders (transmission and air sensitive samples)

Software

• DIFFRAC.SUITE (data collection)
• DIFFRAC.EVA (data processing)
• TOPAS v6
