Instrument Name: X-ray Fluorescence Spectrometer

Model: S8 TIGER II

Manufacturer: Bruker, Germany

Key Technical Specifications

1. Elemental Analysis Range

Qualitative, quantitative, and standard-free analysis of elements from B (atomic number 5), O (atomic number 8) to Am (atomic number 95) in the periodic table.

2. Concentration Range

ppm to 100 wt%.

3.X-ray Generator

Sequential scanning high-voltage generator; maximum power ≥ 4 kW, maximum voltage ≥ 60 kV, maximum current > 170 mA.

4. X-ray Tube

End-window Rh-target ceramic X-ray tube fitted with a non-leaking Be window (thickness ≤ 75 µm); maximum power ≥ 4.2 kW, maximum voltage ≥ 75 kV with 1 kV stepping, maximum current ≥ 200 mA with stepping ≤ 1 mA.

5. Irradiation Mode

Bottom-up irradiation design, supporting fast and cost-efficient analysis of liquid samples and small-quantity powder samples. Equipped with a tube dust shielding assembly.

6. Goniometer

Angular accuracy ≤ 0.001°; angular reproducibility ≤ 0.0001°.

7.Detectors

Flow proportional counter, maximum count rate > 5,000 kcps; scintillation counter, maximum count rate ≥ 4,500 kcps.

Application Scope

Applicable to bulk solid samples and pressed-powder pellets. An integrated helium system is equipped to directly analyze liquid samples and loose powder samples. This rapid, non-destructive method enables identification and quantification of trace elements in various materials.
