Main component and technical parameters
● The detection limit of harmful elements Cd, Pd, Cr, Hg and Br is restricted according to ROHS instruction
Detection limit (Cd, Pd, Cr, Hg, Br): 1ppm
● Si(PIN) or SDD detector
The resolution of detector is one of the main indexes to evaluate the performance of energy dispersion XRF spectrometer.
1. Resolution< 145eV (The lower the resolution, the higher the sensitivity.)
2. Counting rate >1000/S
3. Crystal area > 15m㎡
4. Beryllium window thickness = 0.025mm
5. Detector power< 1.2W
● Multi-channel analyzer Number of channels: 2048 channels
● Power controller
System power control: +5 VDC at 250 mA(1.2 W)
Constant cooling control: 400 VDC
● 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.
