NEX CG II Series

The Rigaku NEX CG II Series are powerful second-generation benchtop energy dispersive X-ray fluorescence (EDXRF) spectrometers. They perform rapid qualitative and quantitative elemental
analyses and address needs across many industries. NEX CG II Series spectrometers serve a broad
range of applications and are ideal for measuring ultra-low and trace element concentrations up to
percent levels.
Unlike conventional EDXRF spectrometers, NEX CG II Series are indirect excitation systems using
secondary targets rather than tube filters. Monochromatic and polarized excitation from secondary
targets vastly improves detection limits for elements in highly scattering matrices like water,
hydrocarbons, and biological materials. Secondary target excitation in full 90° Cartesian Geometry
eliminates background noise. As a result, the NEX CG II Series spectrometers bring a new level of
analytical sensitivity to XRF technology. Users can measure ultra-low and trace element
concentrations, even in challenging sample types.
Models include NEX CG II for excellent spectral resolution for trace peaks or NEX CG II+ for more
demanding applications requiring a higher-powered system.

NEX CG II Series spectrometers are well suited for the following applications:
• Agricultural soil and plant materials
• Finished animal feeds
• Waste oils
• Environmental monitoring
• Pharmaceuticals and cosmetics
• Catalysts
• Monitoring for toxic metals in aerosols on air filters
• Trace heavy metals and rare earth elements (REE)
• Other applications that require a high degree of sensitivity
