The fulcrum of our company
A team dedicated to the control and continuous improvement of chemical processes.
The laboratory is the most precious part of our company. Testing and Improvement are the two cornerstones of laboratory activity. The investments made in training and technologies led, in 2014, to creating a new internal environment entirely dedicated to the control and optimisation of the chemical processes in use. With a twofold objective: to meet the high quality standards required by large fashion houses, and to constantly monitor compliance with the quality attributes of the chemical solutions produced. In the chemical laboratory, tests are carried out to assess the quality of chemical solutions and their potential effects on different materials.
To be more specific, routine analysis takes place in two distinct phases:
- Analysis of the chemical-physical parameters of the solutions for determining the content of metals and organic and inorganic additives (atomic absorption, X-ray fluorescence, ion chromatography, potentiometry).
- Electrolytic deposition tests under standard conditions (electrolysis in Becker/Hull cells).
What is XRF spectrophotometry?
A technique that offers great reliability at sustainable costs
XRF (X-Ray Fluorescence) spectroscopy is a chemical-physical analysis technique based on the analysis of the emission of X-ray fluorescence. This particular technique allows us to discover the elemental composition of a sample from a qualitative and quantitative point of view. This radiation is emitted by the atoms of the element present in the sample, after excitation, obtained by irradiation with X-rays being emitted from a source.
How does XRF Spectrophotometry work?
Going into more detail, the X-rays from the X-ray source strike the electron of the element, exciting it and causing its expulsion. The relaxation of an outermost electron, in order to fill this vacated space, leads to the emission of fluorescence of a specific and univocal X-type radiation. This type of spectroscopic investigation technique is based on Moseley's law, for which the fluorescent X-ray energy is specific to each atom and depends directly on its nature, through the atomic number, Z. As if it were a digital impression of the element. By reading this signal it is therefore possible to establish the qualitative composition of the sample. By evaluating the intensity of this emission, it is possible to obtain quantitative information, relative to each different element present in the sample.
Area of application
The XRF spectroscopy can be used for the analysis of both liquid and solid samples. Thanks to these tecnologies, checking the status of one's bath independently in the electroplating industry is possible. It can also be used to directly control the supply of precious metals or to recover them from processing waste.
