TX 2000 is the state of the art laboratory spectrometer for quantitative multi element trace analysis using Total Reflection X-Ray Fluorescence (TXRF).
TXRF is a type of Energy Dispersive X-Ray Fluorescence (EDXRF) in which the beam strikes the sample, deposited as a thin layer on a carrier, at a very small incidence angle, in order to exploit enhancement given by the total Reflection effect.
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.
TX 2000 Main Features
- TXRF spectroscopy in the same equipment.
- Stepper motors with optical encoders ensure extremely precise angular values.
- Automatic switching of primary beam (MoKa, WLa/Lb and bremsstrahlung 33 keV) using double anode Mo/W X-ray tube, based on innovative software. We select the energy required using an high reflectivity 80% (WLa/Lb/MoKa) multilayer. We can choose also other X-ray tubes and monochromatise the energy that you need.
- Peltier-cooled Silicon Drift Detector with an energy resolution of 124eV FWHM@MnKa (shaping time 1 ms)
- Minimal distance between the sample and the detector (mounted to the axis normal to the plane of the sample).
- Instrumental detection limits for more than 50 elements below 10 pg.
- Helium device to improve the detection limits for the light elements.
- Excellent detection limits (ppt) for a wide range element
- No matrix effect
- Environmental Analysis: water, dust, sediments, aerosol
- Medicine: toxic elements in biological fluids and tissue samples
- 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
- Pigments: ink, oil paints, powder
- Semiconductor Industry: by VPD (vaporphase decomposition)
- Nuclear Industry: measurements of radioactive elements

Written for Windows 7 is the program designed for the control of the TX 2000 System. It includes some new features, like the batch programming of a set of measurements. The program can control different kinds of detectors and devices attached to the instrument. Control panels for scintillation, linear position sensitive detectors and XRF X-GLAB SDD detector are integrated.
