Features of the MiniFlex600

Fig. 1 shows the appearance of the MiniFlex600 main unit. The main unit dimensions are 560(W) x 460(D) x 700(H) mm. With a newly developed X-ray generator, it is possible to obtain measurement data with 1.5 times the X-ray diffraction intensity of the previous model, the MiniFlex II. This makes it possible to obtain diffraction intensity approaching that of full-sized models. Fig. 2 shows an intensity comparison between the MiniFlex600, MiniFlex300 and the previous MiniFlex II model.

MiniFlex600 is used in many fields of industry and research, for substances ranging from inorganic materials such as ceramics and minerals, to pharmaceuticals and other organic materials. It was found that the main component dolomite (CaMg(CO₃)₂) contains trace amounts of calcite (CaCO₃) and barite (BaSO₄).

New sixth generation MiniFlex X-ray diffractometer (XRD) is a multipurpose analytical instrument that can determine: phase identification and quantification, percent (%) crystallinity, crystallite size and strain, lattice parameter refinement, Rietveld refinement, and molecular structure. It is widely used in research, especially in material science and chemistry, as well as in industry for research and quality control. It is the newest addition to MiniFlex series of benchtop X-ray diffraction analyzers from Rigaku, which began with the introduction of the original MiniFlex system decades ago. Read more...
