High power sequential WDXRF spectrometer
Based on years of R&D and production experience on simultaneous wavelength-dispersive X-ray fluorescence spectrometer, Skyray Instrument proudly launched WDXRF Spectrometer WDX-4000, the first sequential wavelength-dispersive X-ray fluorescence spectrometer integrating unique innovation. The performances of WDXRF Spectrometer WDX-4000 meet the requirements of JJG 810-1993 Verification regulation for Wavelength-dispersive X-ray Fluorescence Spectrometers.

Appplications:
It can be used in fields of mineral, cement, steel and environmental protection. By a large number of general designs, WDXRF Spectrometer WDX-4000 provides reliable and economical maintenance to customers in time.

Unique Goniometer design
Innovative and igneoussteel-belt-drive system. This patented design provides no friction, no backlash, stable motion which guarantee the most accuracy angular positioning.
θ/2θ spindle has independent drive system with servo motor and optical encoder feedback.
Permanent magnet synchronous motor(PMSM) providesthe fast and smooth motion.
Optical encoder's 0.0002°resolution and 0.0006 accuracy ensures that the integrated system has excellent performance.

Multi-channel Analyzer of WDXRF Spectrometer
12bits, 80Msps, the most powerful AD sampling system, records signal completely and accurately.
4096 (12bit) channels analyzer based on high speed FPGA architecture and robust DSP algorithm is able to discriminate proper X-ray from stray X-ray.
Energy-dispersive function is additional.

X-ray Tube and HV generator of WDXRF Spectrometer
Standard 4kW power system provides ultra-sensitivity for trace element analysis and a faster speed of analysis.
The thin beryllium window (50um or 75um) provides ultra-high transmission of X-ray, especial to low energy X-ray region.
Max. 60kV and 140mA, (75kV and 160mA is optional) and flexible setting helps analysis method to be much finer.
Dual water cooling circulation system, conductivity of deionized water lower than 1uS by resin increases of tube's service life as long as possible.z
