Xrf for RoHS

                                                 Main component and technical parameters
1. Si(PIN) or SDD detector
The resolution of detector is one of the main indexes to evaluate the performance of energy dispersive XRF spectrometer.
Resolution < 145eV (The lower the resolution, the higher the sensitivity.)Counting rate > 1000/SCrystal area > 15mm2Beryllium window thickness = 0.025mmDetector power < 1.2W
 
2. Multi-channel analyzer
Number of channels: 2048 channels
 
3. Power controller
System power control: +5 VDC at 250 mA (1.2 W)
Constant cooling control: 400 VDC

4. X ray tube
The X-ray tube, specially treated with embedded lead inside is shielded in full range, leaving only the side window for the x ray outlet. The canned insulating oil is used for high voltage insulation and cooling, 0.005 inch Beryllium window, rated consumption power 50W, rated power 50kV. Designed service life >15000h.

5. High voltage generator
Input:  85~265VAC,47~63Hz, Power factor correction.
   1kV~5k V comply to UL85~250VAC input standard
Voltage variation: 0.01% of output voltage from no load to full loadCurrent variation: 0~rated power, 0.01% of output currentRipple: Peak - peak of output voltage 0.25%  Temperature variation: voltage or current setting, 0.01%/oCStability: 0.05%/8h after warming-up for half an hour
6. Automatic filter conversion system
Filters are automatically selected and converted(filter function: The energy spectrum component of the excitation line can be improved to suppress the strong X-ray fluorescence of high content components and improve the measurement accuracy of the elements to be measured.)

7. Radiation shielded system
Newly designed and specially treated X-ray tube with low-radiation Fully enclosed lead plate double shield designAutomatic filtering device for lead plate X - ray interrupters in case of sample unexpected cover openingDelay testing and X-ray warning system

8. The detection limit of harmful elements Cd, Pb, Cr, Hg and Br is restricted according to ROHS instruction
Detection limit (Cd,Pb,Cr,Hg,Br): 2ppm

9. Powerful analysis software workstation
One-touch operation software, simple and easy to use, user does not need professional knowledge. Ergonomic human-machine interfaceOperators do not need to set various test parameters, powerful customized report function..Test data is automatically stored with historical query functionThe most advanced qualitative and quantitative analysis method. Dozens of elements can be analyzed simultaneously.Quick element analysis and the analysis time is adjustable from 30 seconds to 900 seconds.Long standby, automatically reduce tube voltage and tube flow to extend tube life.Temperature control of X ray tube to extend its service life.Monitor instrument operation status in real time and maintain it easily.To prevent the wrong operation of opening the cover of the sample when testing the sample, the software has warning operation prompts, and at the same time shut down the high-voltage power supply.
