Benchtop X-ray diffractometer for phase analysis
New sixth generation MiniFlex benchtop X-ray diffractometer is a multipurpose powder diffraction analytical instrument that can determine: crystalline phase identification (phase ID) 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 the MiniFlex series of benchtop X-ray diffraction analyzers from Rigaku, which began with the introduction of the original MiniFlex XRD system decades ago.
X-ray powder diffraction with HPAD detector
MiniFlex XRD system delivers speed and sensitivity through innovative technology advances, including the HyPix-400 MF 2D hybrid pixel array detector (HPAD) together with an available 600 W X-ray source and new 8-position automatic sample changer.
Hybrid pixel array detector (HPAD)
This new direct photon counting detector enables high-speed, low-noise data collection and may be operated in 0D and 1D modes for conventional XRD analysis and 2D mode for samples with coarse grain size and/or preferred orientation.
XRD accessories enhance your MiniFlex
A variety of X-ray tube anodes – along with a range of sample rotation and positioning accessories, together with a variety of temperature attachments – are offered to ensure that the MiniFlex X-ray diffraction (XRD) system is versatile enough to perform challenging qualitative and quantitative analyses of a broad range of samples, whether performing research or routine quality control. The new (Gen 6) MiniFlex X-ray diffractometer system embodies the Rigaku philosophy of “Leading with Innovation” by offering the world’s most advanced benchtop system for powder diffractometry.
Advanced PDXL powder diffraction software
Each MiniFlex comes standard with the latest version of PDXL, Rigaku's full-function powder diffraction analysis package. The latest version of PDXL offers important new functionality; including a fundamental parameter method (FP) for more accurate peak calculation, phase identification using the Crystallography Open Database (COD), and a wizard for ab inito crystal structure analysis.
MiniFlex X-ray diffractometer history
The Rigaku MiniFlex X-ray diffractometer (XRD) is historically significant in that it was the first commercial benchtop (tabletop or desktop) X-ray diffractometry instrument. When introduced in 1973, the original Miniflex™ benchtop XRD was about one-tenth the size, and dramatically less expensive, than conventional X-ray diffraction (XRD) equipment of the period. The original instrument (Gen 1), and its successor that was introduced in 1976 (Gen 2), employed a horizontal goniometer with data output provided by an internal strip chart recorder. The third generation (Gen 3) benchtop diffractometer, introduced in 1995, was called Miniflex+. It provided a dramatic advance in X-ray power to 450 watts (by operating at 30kV and 15mA) and Windows® PC computer control. Both the Miniflex+ and the succeeding generations of bench diffractometers employ a vertical goniometer and allow the use of an automatic sample changer. The fourth generation (Gen 4) Miniflex II benchtop XRD was introduced in 2006 and offered the advance of a monochromatic X-ray source and a D/teX Ultra 1D silicon strip detector. The fifth generation (Gen 5) MiniFlex600 desktop XRD, introduced in 2012, built upon this legacy with 600W of available power and new PDXL powder diffraction software.

An enclosed sample holder is available for users studying materials that might degrade in the presence of oxygen.
Automatic 8-position sample changer is compact and rugged. Integrated spinning improves particle statistics in polycrystalline sample measurements. Fully automatic alignment. Programmable.
The high temperature attachment can heat a sample to do in-situ powder diffraction measurements under high temperature conditions from ambient to 500°C.
This 1D silicon strip detector is optionally available for fast, high-resolution scanning.
The graphite monochromator optimizes sensitivity by lowering the background level. It improves signal-to-noise by eliminating fluorescence from Mn, Fe, Co, and Ni containing materials.
2D hybrid pixel array detector (HPAD) to collect diffraction image 2 dimensionally. The 2D diffraction images reveal preferred orientation and crystallite size information for the sample together with phase and lattice parameter information
Various sample holder are available to meet the specific needs of particular applications.
The sample rotation stage allows continuous rotation at variable speed of the sample holder to improve particle statistics during powder diffraction measurements.
