X-ray fluorescence spectrometers use high-energy X-rays (or gamma rays) to excite fluorescent radiation from a sample for quantitative chemical or elemental analysis and have many industrial and research applications. Elements with an excitation energy less than the x-ray beam fluoresce and can be counted by a wavelength-dispersive or energy-dispersive spectrometer. The advantages of X-ray fluorescence spectrometers are that there is no need for sample prep (the material can simply be placed in the beam), and that it is a non-destructive analysis technique. This is ideal for fields like archeology, where destructive analytical methods are not an option. X-ray spectrometers are also gaining importance in response to increasing demand for lead testing in consumer products. Speed and sensitivity are prime considerations in choosing an X-ray fluorescence spectrometer. Ease of use and good analytical software are also important.

They deliver rapid, non-destructive multi-element analyses (Na to U) from trace concentrations up to the percent level. The Cartesian configuration and indirect excitation provide increased signal-to-noise, even for challenging samples, making them an excellent choice for industrial quality control to advanced research applications.
NEX CG II Series are multi-purpose elemental analyzers that provide rapid qualitative and quantitative elemental analyses and address needs across many industries. They are suited to chemical analysis in almost any matrix — from oils and liquids to solids, metals, polymers, powders, pastes, coatings, and thin films. Available models are NEX CG II, which offers excellent spectral resolution for trace peaks, and NEX CG II+, designed for more demanding applications requiring a higher-powered system.
Cartesian Geometry and Polarization for Trace Level Sensitivity
Unlike conventional energy dispersive X-ray fluorescence (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, 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.
