Rigaku’s NEX CG II EDXRF for Rapid Elemental Analysis

The NEX CG II from Rigaku is a strong and rapid XRF spectrometer that extends the boundaries of EDXRF technology. It offers quick and non-destructive multi-element analyses (ranging from sodium (Na) to uranium (U)), from trace concentrations up to the percent level.

Thanks to the Cartesian configuration and indirect excitation, the signal-to-noise ratio is increased, even for difficult samples, which makes the NEX CG II a perfect choice for industrial quality control to sophisticated research applications and everything in between.

The NEX CG II is a versatile elemental analyzer that offers quick quantitative and qualitative elemental analyses and fulfills the requirements of various industries. It is appropriate for chemical analysis in nearly any matrix — varying from oils and liquids to solids, polymers, metals, coatings, pastes, powders and thin films.

Cartesian Geometry and Polarization for Trace Level Sensitivity

In contrast to conventional energy dispersive X-ray fluorescence (EDXRF) spectrometers, the NEX CG II is an indirect excitation system that employs secondary targets instead of tube filters. Polarized and monochromatic excitation from secondary targets immensely enhances detection limits for elements in highly scattering matrices such as hydrocarbons, water and biological materials.

Thanks to secondary target excitation in full 90° Cartesian Geometry, background noise is removed. Consequently, the NEX CG II provides a whole new level of analytical sensitivity to XRF technology. Ultra-low and trace element concentrations can be measured even for difficult sample types.
