Features of D8 FOCUS
Simple choices for optimal performance
The focusing Bragg-Brentano geometry with slits provides the best resolution for flat powder samples. For irregularly-shaped samples and non-ambient measurements, the parallel beam geometry with a Göbel mirror is the optimum setup.
You need both? No problem! Optics and sample holders can be exchanged without tools or alignment.
Choose the detector for your application!
The standard detector is the scintillation counter, with high dynamic range and low internal background. If you have fluorescent samples, you can lower that background and increase the sensitivity using the energy dispersive SOL-XE detector.
You need fast results? Sure! The LYNXEYE linear detector can accelerate your measurements by a factor of up to 200!
What information do you get?
X-ray diffraction with the D8 FOCUS can identify and quantify the different phases inside a powder sample. For new materials, you can solve and refine the crystalline structure using the TOPAS software.
The same data also provides information on the crystallite size and the microstrain.
Adding a temperature chamber allows you to perform non-ambient investigations and observe phase changes.
