DW-NP-5010 High Quality Energy Dispersion X-ray Fluorescence Spectrometer XRF
Product Feature
Introduction
DW-NP-5010A energy dispersive XRFhas very wide application. It can do qualitative, quantitative and no sample analysis. Such as block sample, powder or liquid samples, from the 4th element in the periodic table beryllium (Be) to the 92rd element uranium (U), almost all of the elements can be accurately analyzed. The analytical concentration range can be from 0.1 PPM to 100%, and even up to 100% of the elementconcentration can be directly measured without dilution.XRF analysis method has the advantages of simple sample preparation, wide determination range of elements, high determination accuracy, good reproducibility, fast measurement speed (30s-900s), no environmental pollution and no destruction of samples.
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/S
Crystal area> 15mm2
Beryllium window thickness = 0.025mm
Detector power< 1.2W
2. Multi-channel analyzer
Number of channels: 2048 channels
3. Power controllerSystem 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~5kVcomply to UL85~250VAC input standard
Voltage variation: 0.01% of output voltage from no load to full load
Current variation: 0~rated power, 0.01% of output current
Ripple: Peak - peak of output voltage 0.25%
Temperature variation: voltage or current setting, 0.01%/oC
Stability: 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.)
