Fast, affordable at-line and on-line solutions for your elemental analysis needs

If you are seeking a more affordable, efficient way to achieve fast, high-quality elemental analysis without complex setups or extensive sample prep, Rigaku offers a comprehensive range of budget-friendly EDXRF benchtops, whether your needs are routine or advanced. All systems are easy to use with minimal sample prep and provide elemental composition data in minutes. Capabilities range from ultra-low and trace element concentrations up to percent levels, serving many screening and monitoring needs and meeting compliance with various testing methods and standards.

Rigaku EDXRF benchtops include the compact NEX QC Series for routine quality control, the advanced NEX DE for demanding high throughput needs, and the powerful NEX CG II indirect excitation analyser for complex applications and research. All Rigaku EDXRF benchtops are multi-element analysers, giving you the advantage of measuring sulphur, chlorine, metals, and more in oils, fuels, lubricants, and used oil. You have more analytical capabilities and can easily adjust to future applications when needed.

With an intuitive icon-driven touchscreen interface, small footprint, built-in printer, and optional portable carrying case, NEX QC Series analysers provide performance, ease of use, and convenience. The NEX QC and NEX QC+ are small, self-contained, and require no external PC. They are also lightweight and transportable, making them perfect for industrial or remote field environments. NEX QC is ideal for measuring sulphur in oils per ASTM D4294 and methods ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4. The NEX QC+ model offers this and more and is ideal for applications where analysis times are more critical. Additionally, NEX QC+ offers compliance with ISO 13032 for the measurement of ultra-low sulphur in diesel fuel and gasoline.

When you need a high-performance system to certify products quickly and easily, the NEX DE analyser delivers rapid and reliable ultra-low measurements of sulphur and metals. For high-throughput measurement of ULSD, NEX DE offers compliance using the ISO 13032 method and can provide quick ASTM D8252 compliance of nickel and vanadium in crude and residual oil. With this system, you can analyse sulphur, vanadium, iron, and nickel in crude, residual oil, bunker fuels, and other heavy hydrocarbon oils.

NEX CG II is an all-in-one petroleum analyser, offering you superior analytical capabilities that rival larger, more expensive systems. It provides fast, precise measuring and monitoring of ultra-low and trace element concentrations. Unlike conventional EDXRF instruments, NEX CG II uses secondary targets in full 90° Cartesian Geometry, eliminating background noise and delivering exceptionally low detection limits. Its unique 3D optical configuration gives unmatched performance and makes it an attractive analyser for any commercial lab or R&D facility.

Additionally, NEX CG II offers exceptional versatility and meets several international norms and testing criteria for the measurement of sulphur, such as analysis of ULSD per ASTM D7220 and analysis of ultra-low sulphur in gasoline per U.S. EPA Tier 3 Standards. With multi-element analysis capabilities, you can reliably analyse manganese in motor and aviation gasoline at low and ultra-low levels per ASTM D5059 Part D or achieve the lowest chlorine detection limits in crude oil per ASTM D4929 Part C.

For real-time process control needs, Rigaku offers NEX XT, a total sulphur analyser for on-line sulphur analysis, and NEX OL, a multi-element analyser for liquid streams.

NEX XT provides total sulphur measurement from 0.04 to 6 wt% of crude, bunker fuel, fuel oils, and other highly viscous hydrocarbons, including residuums. This versatile, compact, and robust X-ray transmission/absorption (XRT/XRA) process gauge is specifically optimised for the total sulphur analysis needs of refineries, pipelines, blending operations, bunkering terminals, and other storage facilities. NEX XT continuously monitors sulphur at pressures up to 1450 psig and 200°C in custom configurations. It operates as a standalone analyser or provides real-time closed-loop control when tied into a blending or plant-wide automation system.

For liquid stream applications, NEX OL is configurable for use in classified and non-classified areas and can analyse from aluminium to uranium. It is ideal for monitoring cobalt, manganese, and bromine catalysts in PTA and catalysts in liquid streams.
