X-ray Fluorescence (Benchtop WD/TR)

Primini Biofuel

Rigaku’s Primini Biofuel is suitable for phosphorus analysis in biodiesel for EN14214 and ASTM D6751. It is optimized for sub-ppm detection limits of P, S and Cl and features easy operation without chemical treatment of the samples. Easy sample preparation and operation reduces the need for a highly skilled operator. A helium atmosphere is maintained […]


Supermini200 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 (COO) with high resolution and lower limits-of-detection (LLD). […]


The new, next generation Rigaku NANOHUNTER II benchtop total reflection X-ray fluorescence (TXRF) spectrometer enables high-sensitivity ultra-trace elemental analysis of liquids down to parts-per-billion (ppb) concentrations. Total reflection X-ray fluorescence spectroscopy is a method by which an incident beam of X-rays just grazes the sample, delivering low-background noise, high-sensitivity measurement of ultra-trace elements. TXRF for […]

Mini-Z Sulfur

Specifically designed for rapid batch testing of low and ultra-low sulfur diesel (ULSD) and gasoline fuel samples, the compact benchtop Mini-Z Sulfur analyzer is designed for easy use by non-technical personnel. Whether at petroleum pipeline terminals, refineries, or testing laboratories, the robust design is hardened for industrial use with minimal maintenance. Sulfur analysis without gas […]

Mini-Z series

A series of compact benchtop wavelength dispersive XRF analyzers, the Mini-Z series of analyzers are designed for analyzing specific single elements. Since the optics are optimally configured to a particular element, this series allows for high precision and low detection limits. High precision single element analysis Mini-Z can be configured as a Si analyzer (e.g., […]

Micro-Z ULS

Designed for ultra-low level sulfur analysis of diesel, petrol (gasoline) and other fuels, the Rigaku Micro-Z ULS wavelength dispersive X-ray fluorescence (WDXRF) instrument features a novel design that measures both the sulfur peak and the back-ground intensity. The ability to measure and correct for changes in background intensity delivers a better net peak intensity measurement, […]
