GNR - Model TX 2000 -Total Reflection X-Ray Fluorescence (TXRF) Spectrometer

As far as the sample is thin enough (thin film approximation), the tecnique’s main strenghts are:

• simultaneous multi-element analysis from Na to Pu
• no matrix effect
• no matrix-dependent calibration curves
• improved detection limits (LOD) down to ng/g or lower
• minimum amount of sample
• microanalysis capabilities

TX 2000, equipped with an automatic primary beam switching system  (MoKa, WLa/Lb and bremsstrahlung 33 keV), a Silicon Drift Detector (SDD) and an high power X-Ray Tube is the optimal solution for applications in environmental, chemicals and nuclear fields.

• Stepper motors with optical encoders ensure extremely precise angular values.
• Enhanced excitation mode by selection of the most suitable monochromatized energy (W-La/W-Lb/Mo-Ka) provided by the combination of double anode MO/W X-ray tube and W/Si multilayer. Other X-Ray anodes can be monochromatized as well.
• Peltier-cooled Silicon Drift Detector with an energy resolution better than of 133eV (FWHM@MnKa, 1ms peaking time)
• Minimal distance between the sample and the detector (mounted to the axis normal to the plane of the sample).
• Instrumental detection limits below ng/g.
• Helium flux attachment to improve the detection limits for the light elements.
• No matrix effect

• Environmental Analysis: water, dust, sediments, aerosol (ISO/TS 18507:2015, ISO 20289:2018)
• Medical/Pharma: toxic elements in biological fluids and tissue samples, catalyst residues
• Forensic Science: analysis of extremely small sample quantities
• Pure chemicals: acids, bases, salts, solvents, water, ultrapure reagents
• Oils and greases: crude oil, essential oil, fuel oil, gasoline, jet fuel
• Pigments: ink, oil paints, powder
• Nuclear Industry: measurements of radioactive elements
