NEX CG II – A New Level of Analytical Sensitivity for Petroleum Analysis Applications

Jul 20 2021

NEX CG II is a new, multi-element, multi-purpose benchtop analyser that delivers rapid qualitative and quantitative elemental analyses and addresses the needs of many petroleum analysis applications. This powerful, second-generation energy dispersive X-ray fluorescence (EDXRF) spectrometer offers exceptional versatility. It provides non-destructive analysis of sodium to uranium in almost any matrix and is an ideal tool for measuring ultra-low and trace element concentrations up to percent levels.

Multi-application, Multi-element Analyser

NEX CG II is an all-in-one analyser — users can measure sulphur and chlorine simultaneously from one sample pour. They can measure sulphur, nickel, vanadium, and iron at the same time. Measure and monitor ultra-low sulphur concentrations in diesel and other petroleum products, or quickly analyse other trace minor and major elements in crude, lube oils, waste oil, and cutting fluids.

NEX CG II is well suited for ASTM and international compliance for ultra-low sulphur applications, such as testing ultra-low sulphur in diesel (ULSD) and meeting Tier 3 gasoline requirements per ASTM D7220. NEX CG II delivers the lowest chlorine detection limits for ASTM D4929 compliance using Part C methodology and easily meets ASTM D5059 Parts A and C using the Bi internal standard method to measure lead in gasoline samples.

  • Analysis of Ultra-low Sulphur Diesel (ULSD) for ASTM & International Compliance
  • Analysis of Gasoline Sulphur for U.S. EPA Tier 3 Standards per ASTM D7220
  • Ultra-low Chlorine in Crude Oil per ASTM D4929 Part C
  • Analysis of Lead in Gasoline per ASTM D5059
  • Analysis of Other Elements in Crude & Residual Oil
  • Certify Products ASTM D8252 and ASTM D4294 Quicker & Easier

Unique Cartesian Geometry Optical Kernel for a New Level of Analytical Sensitivity

NEX CG II features a unique three-dimensional (3D) close-coupled Cartesian Geometry optical kernel that dramatically increases the peak-to-background ratio. This results in a spectrometer capable of trace element analysis — even in challenging sample types.

Unlike conventional EDXRF spectrometers, NEX CG II is an indirect excitation system using secondary targets rather than tube filters. The Cartesian Geometry optical kernel employs monochromatic and polarized excitation from secondary targets to remove background noise, resulting in exceptionally low detection limits. As a result, NEX CG II brings a new level of analytical sensitivity to XRF technology and petroleum analysis applications.

Applied Rigaku Technologies, Inc. offers a complete line of benchtop and process EDXRF instruments for petroleum analysis applications. Rigaku EDXRF products serve many screening and monitoring needs and meet compliance for multiple testing methods and standards. For more information, contact us by email.
