The Eagle-III Energy Dispersive X-Ray Fluorescence Spectrometer

This spectrometer is used to determine the element content by quantitative and semiquantitative method. At present, in our laboratory, it mainly used to appraise the ancient ceramics by its chemical compositions.

The mainly performance index

The range of element

6C-92U, usually, it just can determine the element which atomic number greater than 11 in normally analysis.

The range of element detected density

PPM--100%

The detector

Si(Li) detector, active area is 80 mm2, and cooled with liquid nitrogen, detecting synchronal from Na to U.

HV-Generator Spellman

Max. Power 40W, Max.outpt voltage 40 KV, Max. Current 1000µA, stability of voltage and current is better than 0.01%.

X-ray tube

Beryllium window, Max. Power 40W

Angular instrument

the accuracy of 2θ is 0.0025’’, the repeatability of 2θ is 0.0001’’, scanning velocity of 2θ is 0.0001-2°/s and optional.

The sample acquirement: Max. Height and Max. Width is all 330mm.

The thermal dilatometer

The thermal dilatometer is used to determine the sample’s movement during heat processing and supply the c-DTA calculated function. The firing temperature, linearity movement, expansion factor, softening point and so on all can study by this dilatometer.
