The Rigaku NEX CG II is a multi-element, multi-purpose benchtop energy dispersive X-ray fluorescence (EDXRF) spectrometer that performs rapid qualitat
This article demonstrates Cartesian Geometry EDXRF for the measurement of lead (Pb) in gasoline per ASTM D5059 using the Bi internal standard method Part C (ultra-low Pb) and Part A (high Pb). Cartesian Geometry EDXRF also offers compliance for ULS.
The analysis of organic chloride in crude using MEDXRF (Monochromatic EDXRF) gives superior performance for ASTM D4929 Part C, and complies with other ASTM, EPA, and International requirements critical to the petroleum industry.
The NEX CG II gives the industry a reliable tool for measuring ULSD using full polarization in 90° Cartesian Geometry EDXRF. Polarization creates extremely low background in the measurement, allowing for very low detection limits for reliable measurement.
