Sequential WDXRF spectrometer

Based on years of R&D and production experiences on simultaneous wavelength-dispersive X-ray fluorescence spectrometer, Skyray Instrument proudly launched WDX-4000, the first sequential wavelength.dispersive X-ray fluorescence spectrometer which integrates unique and remarkable innovations. The performances of WDX-4000 meet the requirements of JJG 810-1993 Verification regulation for Wavelength-dispersive X-ray Fluorescence Spectrometers. It can be used in fields of geology, cement, steel and environmental protection, etc. By a large number of general designs, WDX-4000 provides reliable and economical maintenance to customers in time.

Highlights:
Unique Goniometer design
Innovative and igneous steel-belt-drive system. This remarkable design provides no friction, no backlash, stable motion which guarantee the most precise angular positioning
0/20 spindle has independent drive system with servo motor and optical encoder feedback
Permanent magnet synchronous motor (PMsM) provides the fastest and smoothest motion
Optical encoders with 0.0001° resolution and 0.0006° accurary ensure that the integrated system reaches excellent performance

Multi-channel Analyzer
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 noise and stray light
Energy-dispersive function is additional

X-rayTube and HV generator
 Standard 4kW power system gives the highest sensitivity for trace element analysis and a higher speed of analysis
The thin beryllium window(50um or 75um) provides ultra-high transmission of X-ray, especial to lowenergy region
Max. 60kV and 140mA,(75kV and 150mAis optional) and flexible setting helps analysis method to be much finer
Dual water cooling circulation system, conductivity of deionized water kept much lower than 1us by resin increases of tube's service life as long as possible
