under standard conditions (Becker/Hull cells electrolysis).
What is XRF ray fluorescence spectrometry?
A techinique that offers great results at sustainable costs
XRF (X Ray Fluorescence) spectroscopy is a chemical-physical analysis technique based on the analysis of X-ray fluorescence emission. This particular technique enables discovering the elemental composition of a sample from a qualitative and quantitative point of view. This radiation is emitted by the atoms of the element located in the sample, following an excitation, obtained through irradiation with X-rays from a source.
How does XRF fluorescence spectrometry work?
Going into detail, the X-rays of the X-ray source strike the electron of the element, exciting it and causing it to be expelled. The relaxation of an outermost electron, in order to fill this vacancy, leads to the emission of a specific and unique X-type radiation fluorescence. This type of spectroscopic investigation technique is in fact based on Moseley’s law, according to which the energy of fluorescent X-rays is specific for each atom and directly depends on the nature of its atomic number (Z). As if it were a fingerprint of the element. By reading this signal it is therefore possible to establish the qualitative composition of the sample. By assessing the intensity of this emission, it is possible to obtain quantitative information, relating to each different element in the sample.
SCOPES OF APPLICATION
The XRF analytical instrumentation can be used for the analysis of both liquid and solid samples. Therefore, within the electroplating industry, thanks to these instruments, it is possible to check the status of the baths autonomously and independently. It can also be used for direct control of metal supplies.
