Huawei Instruments, Shenzhen Huawei Instruments
X-ray fluorescence spectrometer Ux-220
Economy, accuracy, and exceptional benefits
Quickly respond to RoHS&WEEE&halogen-free directives, effectively control environmental risks of restricted substances
Element detection
RoHS testing:
Users can easily detect and control the six types of substances controlled by RoHS.
Pb, Cd, Hg, hexavalent Cr (total Cr tested) PBB, PBDE (total Br tested).
Halogen free testing:
Excellent hardware design and sophisticated software spectroscopic methods enable precise testing of chlorine (Cl) elements. The detection limit is as low as ≤ 60ppm.
Open working curve
Users can easily establish a working curve for risk materials based on their own material conditions, comprehensively improving the correspondence between the working curve and the tested material. Thus significantly improving the detection accuracy of risk substances.
　　Huawei Instruments, Shenzhen Huawei InstrumentsAnalysis time
Different detection times can be set according to the type of sample, and the detection time can be automatically adjusted according to the sample size to ensure the required detection accuracy.
XRF application - halogen-free testing
The main reasons for the differences in the measurement of chlorine (Cl) element before and after optical path optimization are as follows:
① Due to the low fluorescence photon energy of chlorine (Cl) element (2.6KeV), air will have a significant absorption effect on the fluorescence photons, thereby reducing the fluorescence intensity and significantly lowering the measurement accuracy.
② The interference of inert gas element argon (Ar) in the air on chlorine (Cl) element can also have a significant negative impact on measurement accuracy.
