X fluorescence spectrum, XRF (energy dispersive X-ray fluorescence spectrometer)
Can be scattered X-ray fluorescence spectrometer definition
X-ray fluorescence spectrometry is a rapid and simultaneous determination of multiple elements of the instrument. When the sample is irradiated with X-rays, the electrons in the inner shell (K, L, or M layers) of each elemental atom are excited to be driven out of the atom to cause electronic transition and to emit characteristic X-ray fluorescence of the element. Each element has its characteristic wavelength X-ray. Energy dispersive X-ray fluorescence spectrometer (EDXRF) utilizes the characteristic that fluorescent X-ray has different energy, and the detector's own energy resolving ability can distinguish the detected X-ray.
Can scattered X-ray fluorescence spectrometer works
The characteristic X-rays generated by the light source sample directly enter the detector. The detector converts the optical signal into an electrical signal and the pulse output by the main amplifier is sent to the ADC (analog-to-digital converter) where the analog signal of the pulse amplitude is converted into The digital signal, the resulting digit, serves as the address to which the MCA is connected. From these addresses, different pulses, x-ray energies, are then separated and the corresponding number of pulses recorded.
