Rigaku’s NEX CG II is a robust and fast XRF spectrometer capable of extending the boundaries of EDXRF technology. It provides fast and non-destructive multi-element analyses (from sodium (Na) to uranium (U)), ranging from trace concentrations to percent levels.
The Cartesian configuration and indirect excitation increase the signal-to-noise ratio, even for complex samples. This makes the NEX CG II an ideal solution for applications from industrial quality control to the most advanced research applications.
The NEX CG II is a flexible elemental analyzer that has been designed specially to provide fast qualitative and quantitative elemental analyses satisfying the needs of numerous industries. The system is suitable for chemical analysis in almost all matrices, ranging from oils and liquids to solids, metals, polymers, coatings, powders pastes and thin films.
Cartesian Geometry and Polarization for Trace Level Sensitivity
When compared to conventional energy dispersive X-ray fluorescence (EDXRF) spectrometers, the NEX CG II uses an indirect excitation that uses secondary targets rather than tube filters. The polarized and monochromatic excitation obtained from secondary targets significantly improves the detection limits for elements lying in high scattering matrices like water, hydrocarbons and biological materials.
Since the secondary target excitation is in full 90º Cartesian Geometry, it helps eliminate the background noise. Thus, the NEX CG II offers a completely new grade of analytical sensitivity to XRF technology. The system is capable of performing ultra-low and trace element concentration measurement even on complicated sample types.
