Supermini200 – Benchtop Sequential WDXRF Wavelength Dispersive X-Ray Fluorescence Spectrometer

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.
