X-ray fluorescence spectrometers use high-energy X-rays (or gamma rays) to excite fluorescent radiation from a sample for quantitative chemical or elemental analysis and have many industrial and research applications. Elements with an excitation energy less than the x-ray beam fluoresce and can be counted by a wavelength-dispersive or energy-dispersive spectrometer. The advantages of X-ray fluorescence spectrometers are that there is no need for sample prep (the material can simply be placed in the beam), and that it is a non-destructive analysis technique. This is ideal for fields like archeology, where destructive analytical methods are not an option. X-ray spectrometers are also gaining importance in response to increasing demand for lead testing in consumer products. Speed and sensitivity are prime considerations in choosing an X-ray fluorescence spectrometer. Ease of use and good analytical software are also important.

| Description | The new Supermini200 has improved software capabilities as well as a better footprint. As the world's only high-power benchtop sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis of oxygen (O) through uranium (U) of almost any material, the Rigaku The new Supermini200 has improved software capabilities as well as a better footprint. As the world's only high-power benchtop sequential wavelength dispersive X-ray fluorescence (WDXRF) spectrometer for elemental analysis of oxygen (O) through uranium (U) of almost any material, the Rigaku Supermini200 uniquely delivers low cost-of-ownership (COA) with high resolution and lower limits-of-detection (LLD).
Low cost of ownership
Not only is the Rigaku Supermini200 an affordable choice for your XRF elemental analysis needs, the running costs are also low. P10 gas for the flow proportional detector is the only consumable. The Supermini200 does not require a source of cooling water, plumbing, or an external chiller, thereby decreasing system maintenance and lowering the overall lifetime cost of ownership of the system and yearly budgets for consumables and maintenance.
Superior light element performance
Analyzing complex matrix materials with a wide range of light and heavy elements, from trace to high concentration levels, is the instrument's core competency. Rigaku Supermini200 delivers high sensitivity for light elements with superior spectral resolution for resolving line overlaps in complex matrices without the need for deconvolution. Analyzing low concentration levels of light elements (F, Na, Mg, Ca, Si, Al, and P) is easy.
High power X-ray tube
Supermini is the only high powered (200 W) X-ray tube benchtop WDXRF system, providing excellent excitation resulting in lower detection limits and shorter measurement times. A unique and proprietary optical system is also employed to enhance sensitivity beyond the gains of the tube power.
