Introduction
LR-WDX200 Compact Multi-channel X-ray Fluorescence Spectrometer,with configuration of 10 fixed channels and capability to analyze 10 elements simultaneously,is able to conduct elemental analysis of arbitrary ten elements from Na to U based on the users' requirements.This instrument is widely used in cement,steel,powder metallurgy,coal,petroleum,kaolin,glass,refractory materials,environment protection and accordingly an ideal choice for quality control in large and middle-scaled enterprises.
Excellent qualities
Rapid and non-destructive analysis of powder and bulk samples
Multi-channel high speed MCA offers timely measurement of every element peak,benefiting not only instrument debugging and failure diagnosis but also the enhancement of stability of the instrument.
Compared with sequential scan large power spectrometers,GA-WDX200 gains adequate analysis precision even when lower power and equal measurement time are adopted,which not only endows the instrument with high cost performance,but also prevents wearing of the goniometer, prolongs the service life of X-ray tube,minimize failures of the high voltage power supply and reduce the maintenance cost of the whole instrument.
Element characteristic X-ray radiation
Different elements have extra-nuclear electronic orbitals of different binding energies,as a result, they give off X-ray photons carrying energies different from each other when excited,that is,each element emits X-ray at its own special energy,representing the characteristic of this element and accordingly called characteristic X-ray.Characteristic X-ray of each element has its specific wavelength;so when we detect X-ray of specific wavelength,we can identify the presence of the interested element in a sample.
Principle of Wavelength Dispersive Spectroscopy
When many elements coexist in a sample and get irradiated by primary X-ray emitted from the X-ray tube, they will emit their corresponding characteristic X-rays, which in general are termed as X-RAY FLUORESCENCE. To separate and measure characteristic X-ray of these elements is called X-ray Fluorescence Spectroscopy
As characteristic X-rays of different elements have specific wavelengths, they can be separated by using Crystal Difraction based on Bragg Equation. This kind of spectroscopy is called Wavelength Dispersive Spectroscopy
Bragg Equation:2dSinθ=n λ
Where d is the interplanar spacing of the lattice planes of the crystals,O is the angle of incidence and diffraction, λ is the wavelength of the incident radiation,N is the order of diffraction and is integer.
Advantages of the Software
1.Self-developed software system for X-ray Fluorescence Analyzers,applicable to windows operating system
2.Easy manipulation realized by operating interface in all Chinese language
3.With innovative technology of full spectrum analysis,every spectrum line can be timely traced and corrected,which greatly improves the repeatability and stability of quantitative analysis and also serves as intuitive evidence of instrument status diagnosis.
