Ultra-Low Sulphur Analysis in Fuels
New Benchtop EDXRF Elemental Analyser
For more demanding applications, or for situations where analysis time or sample throughput is critical, Rigaku (USA) offers the new NEX QC+ spectrometer. Employing the next generation silicon detector technology, the enhanced NEX QC+ affords significant improvement in elemental peak resolution and counting statistics, resulting in superior calibrations and measurement precision for the most challenging measurements.
Designed for ultra-low level sulphur analysis of diesel, petrol (gasoline) and other fuels, the Rigaku (USA) Micro-Z ULS wavelength dispersive X-ray fluorescence (WDXRF) instrument features a novel design that measures both the sulphur peak and the background intensity. The ability to measure and correct for changes in background intensity delivers a better net peak intensity measurement, resulting in superior calibrations and enhanced real world precision. Rigaku Micro-Z ULS complies with ASTM 2622-10, ISO 20884 and JIS K2541-7 methods.
Rigaku Micro-Z ULS is the ideal solution for sulphur analysis of petroleum based fuels, with a lower limit of detection (LLD) of 0.3 ppm sulphur. Employing robust fixed optics in a vacuum environment, and featuring a specially designed doubly curved RX-9 analysing crystal, the Micro Z ULS delivers consistent high sensitivity measurements. Specifically designed for non-technical users, all operations – from calibration through routine analysis – can be performed via the easy-to-use interface and the analyser can be powered by any standard “wall” AC outlet.

Benchtop WDXRF Spectrometer
Specifically designed for routine quality control applications, the new Rigaku NEX QC+ features an intuitive "icon-driven" touch screen interface for easy operation and a built-in printer for convenience. The shuttered 50kV X-ray tube and Peltier cooled semiconductor detector deliver exceptional short-term repeatability and long-term reproducibility with excellent element peak resolution. This high voltage capability (50 kV), along with multiple automated X-ray tube filters, provides a wide range of applications versatility and low limits-of-detection (LOD).

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 (USA) Supermini200 uniquely delivers low cost-of-ownership (COA) with high resolution and lower limits-of-detection (LLD).
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.
Analysing 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. Analysing low concentration levels of light elements (F, Na, Mg, Ca, Si, Al, and P) is easy.
