Multi-purpose Petroleum Analyser with Ultra-low Detection Limits

Feb 15 2022

Rigaku's highly versatile multi-element NEX CG II analyser offers fast, reliable measuring and monitoring for ultra-low sulphur applications, chlorine and metals in crude, manganese and lead in gasoline — and much more. It provides rapid, non-destructive qualitative and quantitative elemental analyses of sodium to uranium in almost any matrix. NEX CG II is an ideal tool for measuring ultra-low and trace element concentrations up to percent levels.

Multi-application, Multi-element Spectrometer

NEX CG II is a powerful, multi-purpose benchtop EDXRF offering exceptional versatility for the petroleum industry. It is well suited for ASTM and international compliance to test ultra-low sulphur in diesel (ULSD) and meet Tier 3 gasoline requirements per ASTM D7220. Users can reliably analyse for manganese in MoGas (motor gasoline) and AvGas (aviation gasoline) at low and ultra-low levels per ASTM D5059 Part D and easily meet ASTM D5059 Parts C and A compliance using the Bi internal standard method to measure lead in gasoline samples. NEX CG II also delivers the lowest chlorine detection limits for ASTM D4929 compliance using Part C methodology.

NEX CG II addresses the needs of many petroleum analysis applications. It serves many screening and monitoring requirements and offers compliance for multiple testing methods and standards.

  • Analysis of ultra-low sulphur diesel (ULSD) per ASTM D7220
  • Analysis of ultra-low sulphur in gasoline per U.S. EPA Tier 3 Standards
  • Ultra-low chlorine in crude oil per ASTM D4929 Part C
  • Analysis of lead in gasoline per ASTM D5059 Part C and A
  • Analysis of manganese in gasoline per ASTM D5059 Part D
  • Analysis of metals in crudes and residual fuels per ASTM D852

Unique Cartesian Geometry Optical Kernel & Advanced Fundamental Parameters Software

Many options are available for measuring sulphur and other elements in petroleum products, but what makes NEX CG II standout is its advanced three-dimensional (3D) Cartesian Geometry optical kernel.

NEX CG II is an indirect excitation energy dispersive X-ray fluorescence (EDXRF) system that uses secondary targets rather than tube filters. Monochromatic and polarised excitation from secondary targets in full 90° Cartesian Geometry eliminates background noise and delivers exceptionally low detection limits.

This unique optical kernel, combined with Rigaku's advanced RPF-SQX Fundamental Parameters (FP) software, delivers the most sensitive EDXRF measurements in the industry. In markets where calibration standards can be expensive and difficult to obtain, RPF-SQX with Matching Libraries reduces the number of standards required, significantly lowering the cost of ownership.

Applied Rigaku Technologies, Inc. engineers, manufactures, and distributes Rigaku EDXRF products worldwide. The company specialises in EDXRF benchtop and on-line elemental analysers serving upstream and midstream for in-field use and downstream for refineries and commercial labs.
