XRF ROHS Spectrometer

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 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~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% 

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.)

7.  Radiation shielded system

l Newly designed and specially treated X-ray tube with low-radiation

l Fully enclosed lead plate double shield design

l Automatic filtering device for lead plate

l X - ray interrupters in case of sample unexpected cover opening

l Delay 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): 1ppm

9.  Powerful analysis software workstation 

One-touch operation software, simple and easy to use, user does not need professional knowledge. 

Ergonomic human-machine interface

Operators do not need to set various test parameters, powerful customized report function.

Test data is automatically stored with historical query function

The most advanced qualitative and quantitative analysis method.

Dozens of elements can be analyzed simultaneously.

10. Type of sample analysis
Can directly detect the solid, liquid, powder, no complex sample preparation process, direct nondestructive analysis of the sample.
