The NEX CG II Series are multi-element, multi-purpose analyzers, ideal for measuring ultra-low and trace element concentrations into the percent levels. Unlike conventional EDXRF spectrometers, NEX CG II Series are indirect excitation systems using secondary targets rather than tube filters.  NEX CG II Series achieve superior analytical power with either a 50 kV 50 W (NEX CG II) or 65 kV 100 W (NEX CG II+) end-window palladium-anode X-ray tube, five secondary targets covering the complete elemental range sodium through uranium (Na – U), and a high-throughput large-area silicon drift detector (SDD). This unique optical kernel, combined with Rigaku’s advanced RPF-SQX Fundamental Parameters software, delivers the most sensitive EDXRF measurements in the industry.
