Self-contained NEX QC⁺ with built-in printer.
Rigaku NEX QC delivers rapid qualitative and quantitative
determination of major and minor atomic elements in a wide variety of
sample types:
• Analyze ₁₁Na to ₉₂U non-destructively
• Solids, liquids, alloys, powders and thin films
• 50 kV X-ray tube
• High resolution SDD detector
• Smartphone style user interface
• Multiple automated tube filters
• Convienient built in thermal printer
• Unmatched performance-to-price ratio
For more demanding applications, or for situations where analysis time or sample throughput is critical, Rigaku 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.
EDXRF for quality control applications
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 analysis of sulfur in ULSD (ultra-low sulfur diesel) is
demonstrated as per standard test method ISO 13032. Regulations around the world have limited the amount of sulfur in
various fuels oils with particular attention to diesel fuel. For many years road diesel has been limited to a maximum sulfur
concentration between 10-15 ppm, depending on the global region. Now these limits are expanded to all diesel fuel, including use in
large engines and off-road diesel engines. The results shown here indicate the Rigaku NEX QC⁺ EDXRF analyzer gives excellent performance for the measurement of ULSD as per standard test method ISO 13032. The versatility of the NEX QC⁺ also make it
an ideal tool for the measurement of many other elements and oil matrices as well, such as lube oils, wear metals in oils, used oil and waste oil, and other elemental analysis needs throughout the petroleum industry.
The measurement of Pt, Rh and Pd in recycled automotive catalytic converters is demonstrated
using the Fundamental Parameters (FP) approach. Used catalytic converters are collected and recycled
in order to reclaim the precious metals Pt, Rh and Pd. Typically, the entire honeycomb core is
removed and ground into fine powder. Once in powder form, the precious metal catalysts can be
extracted, or the powder can be sold to a refiner.
The honeycomb core is typically ceramic, containing combinations of the elements Al, Si, Fe, Zn, Sr, Zr, Ba, La
and Ce. Some cores can be made of a stainless steel honeycomb and so would contain higher Fe and other
metals. Catalyst material may also be high in Pb content, in regions where leaded gasoline is still used.
Because all of these matrix elements can occur at various levels, the fundamental parameters software with
matching Library offers quick direct analysis, of powdered catalytic converter cores, without the need for a large
suite of calibration standards.
The analysis of finished Portland cement is demonstrated
using the empirical approach.X-ray fluorescence (XRF) spectroscopy is a well established
technique used in cement plants around the world. The
technique is ideal for quality control (QA/QC) throughout the
cement production process. Energy dispersive X-ray
fluorescence (EDXRF) spectrometry is a routinely employed
screening and quality control tool employed to ensure proper
composition of incoming feedstocks, raw meal mixture
balances, addition of gypsum and throughout the
manufacturing process. EDXRF analyzers are also
commonly deployed as backup instruments for WDXRF
spectrometers used for final QC and certification.
