TXRF Total Reflection X-ray Fluorescence Spectrometer – TTX3000S
TXRF Total Reflection X-ray Fluorescence Spectrometer – TTX3000S is a highly portable device specifically crafted for elemental and trace analysis. This advanced spectrometer achieves high-sensitivity detection even in extremely low-noise environments, delivering fast, precise quantitative and semi-quantitative multi-element trace analysis for a range of substances, including liquids, suspensions, solids, and contaminants.
With a design focused on high performance, user-friendliness, environmental responsibility, and cost-effectiveness, the TTX3000S is an invaluable tool for applications in scientific research, quality assurance, and environmental monitoring.
Working Principle
The TTX3000S instrument operates on total reflection X-ray fluorescence spectroscopy (TXRF), utilizing a high-brightness, micro-focus fixed-target light source to produce a precise X-ray beam. This beam is refined further by a multi-layer monochromator that reflects the X-rays twice, narrowing the beam's energy range to an exceptionally focused band. The resulting thin beam strikes a flat sample carrier at an extremely shallow angle (less than 0.1°), ensuring complete reflection. The sample then emits characteristic fluorescence, which is captured by an energy-dispersive X-ray detector. Due to the minimal distance between the detector and sample carrier, the TTX3000S achieves high fluorescence detection efficiency while reducing the air’s absorption of X-rays, enhancing overall sensitivity.

Analysis of Extremely Small Sample Amounts at the ng-μg Level
This method enables accurate analysis with only minimal sample quantities, making it highly suitable for situations where sample volume is limited.
Simultaneous Multi-Element Analysis
The instrument is capable of detecting multiple elements at once, including eight primary heavy metals like chromium and lead. With flexible detection settings, it can expand to analyze nearly 30 elements based on testing needs, significantly reducing analysis time.
LOD as Low as ppb Level
Achieving detection limits down to the parts-per-billion (ppb) level, this instrument surpasses the capabilities of traditional XRF, opening up vast potential for trace element analysis.
Rapid 2-Minute Processing Time
With just a 2-minute processing requirement and no need for calibration or sample digestion, this instrument offers exceptional convenience and efficiency, especially suited for on-site analysis.
Low Operating Costs
By directing the X-ray beam at a grazing angle, the instrument minimizes scattering and fluorescence background, resulting in lower background noise and dramatically reducing the detection limit. This efficiency contributes to significantly lower operating costs.
