Multi-purpose Petroleum Analyser with Ultra-low Detection Limits

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.
