Compliance with Multiple Testing Methods for Fuels and Crudes Using One Instrument

Measuring and monitoring for sulphur and other elements in fuels and crudes is an essential part of the petroleum industry. Elemental analysis is imperative for processing purposes, meeting contract agreements, as well as complying with international regulations and mandates around the world. To meet these demands, Rigaku's highly versatile multi-element NEX CG II analyser offers compliance for multiple testing methods and standards and serves many screening and monitoring requirements.

NEX CG II is an all-in-one petroleum analyser offering fast, reliable measuring and monitoring for ultra-low sulphur applications 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 Analyser for ASTM, EPA, and International Compliance

NEX CG II offers users exceptional versatility. It meets several international norms and testing criteria for the measurement of sulphur in petroleum oils, fuels, and ultra-low sulphur in diesel (ULSD).

• Analysis of ultra-low sulphur diesel (ULSD) per ASTM D7220
• Analysis of ultra-low sulphur in gasoline per U.S. EPA Tier 3 Standards
• Analysis of sulphur in automotive fuels per ISO 13032, IP 532, and EN ISO 20847
• Analysis of sulphur in petroleum products per ASTM D4294 and EN ISO 8754

With multi-element analysis capabilities, 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.

• 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 D8252

Cartesian Geometry EDXRF Achieves Exceptionally Low Detection Limits
and Offers an Unmatched Price/Performance Ratio

NEX CG II is an indirect excitation energy dispersive X-ray fluorescence (EDXRF) system. Unlike conventional EDXRF instruments, NEX CG II 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 three-dimensional (3D) Cartesian Geometry optical configuration offers users superior analytical capabilities, rivaling larger, more expensive systems and replacing the need for multiple single-element benchtops. This unmatched performance and smaller footprint make NEX CG II an attractive system for any commercial lab or R&D facility. It is easy to use for non-technical operators and powerful enough for experts.
