Since 1951, Rigaku has been at the forefront of analytical and industrial instrumentation technology. Rigaku and its subsidiaries form a global group focused on life sciences and general purpose analytical instrumentation. With hundreds of major innovations to its credit, Rigaku and its subsidiary companies are world leaders in the fields of small molecule and protein crystallography, X-ray spectrometry and diffraction, X-ray optics, as well as semiconductor metrology. Rigaku employs over 1,400 people globally.
Sulfur in distillates, diesel, heavies, crude and marine fuel
The new low cost Rigaku NEX QC benchtop EDXRF delivers compliance with the ASTM D4294 sulfur method (also methods: ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4) with an easy-to-learn software interface in a robust package specifically designed for the petroleum industry. Optimized for routine determination of sulfur in petroleum, including crudes, heavies, bunker fuel and for upgrading operations, the instrument features an intuitive and modern "icon-driven" touch screen, Smartphone-style interface for easy operation and a built-in thermal printer for convenience. In addition, the new Rigaku NEX QC+ instrument delivers compliance with the ISO 13032 sulfur method for ULSD and the Rigaku NEX CG benchtop EDXRF is compliant with the ASTM D7220 method for ULSD.
Analyze sulfur plus other elements from Na through U
All Rigaku EDXRF analyzers have inherent multi-element analysis capability. For example, Rigaku NEX QC is capable of measuring more than just sulfur. Multi-element analysis is important for detecting crude oil contamination or adulteration by the presence of salt and other chlorine-bearing compounds. Left undetected, the presence of Cl can bias the S reading high, and potentially leave the presence of Cl unnoticed. NEX QC has the ability to detect Cl and other elements, and correct for the presence of Cl so that it does not bias the S reading.
On-line, real time process sulfur gauge
Rigaku NEX XT is the next generation process gauge for high-level total sulfur measurement (0.02% to 6% S) 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 optimized for the total sulfur analysis needs of refineries, pipelines, blending operations, bunkering terminals and other storage facilities.
