Rigaku NEX CG delivers rapid qualitative and quantitative determination of major and minor atomic elements in a wide variety of sample types — with minimal standards.
Unlike conventional EDXRF analyzers, the NEX CG was engineered with a unique close-coupled Cartesian Geometry (CG) optical kernel that dramatically increases signal-to-noise. Monochromatic or polarized excitation from secondary targets, instead of conventional “noisy” white radiation (Bremsstrahlung) direct excitation, vastly improves detection limits for elements in highly scattering matrices like water, hydrocarbons, and biological materials. The resulting dramatic reduction in background noise, and simultaneous increase in element peaks, affords a spectrometer capable of routine trace element analysis even in difficult sample types. Up to five secondary targets cover the complete elemental range (Na – U) with optimized ...
