General purpose X-ray diffractometer DRON-8 with vertical theta - theta goniometer and sample horizontal position enables to perform X-ray diffraction analysis of phase composition, structural state and orientation of heavy large-size and irregular-form samples.Instrument DRON-8 has high technical and operational characteristics as compared with DRON-7 model being issued these days. Goniometer has a changeable radius (180-250 mm), angle position reproducibility is not more than 0.001 deg., automatic adjustment of the sample plane is provided; there are 6 algorithms for independent and synchronous moving of X-ray tube and detector that covers all known methods of XRD analysis. There is a number of options that are possible for DRON-7. Four-axles holder for large samples (xy-scanning, z-moving, -rotation) is added to allow to analyse large objects of different shapes (plates, single crystals and other odd-shaped samples) both for the analysis of their phase composition and structural state, and for control of their surface orientation in relation to the crystallographic axes.Production of diffractometers DRON-8 started in 2010.
