NEX CG II +

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 multiple industries. The NEX CG II Series serves a broad range of applications and is ideal for measuring ultra-low and trace element concentrations up to percent levels.

Unlike conventional EDXRF spectrometers, the NEX CG II Series uses indirect excitation systems with secondary targets instead of tube filters. Monochromatic and polarized excitation from secondary targets significantly 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 brings 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 the NEX CG II for excellent spectral resolution of trace peaks and the NEX CG II+ for more demanding applications requiring higher power.

The 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
