Process to determine light elements content of steel an alloys

The present invention refers to the process of determination of light elements, i.e., molar mass lower than 23, within inorganic materials, by means of spectra analysis between 5 keV and 22 keV, obtained from these materials when exposed to X radiation. Particularly, the invention refers to the dire...

Beschreibung
Zusammenfassung:	The present invention refers to the process of determination of light elements, i.e., molar mass lower than 23, within inorganic materials, by means of spectra analysis between 5 keV and 22 keV, obtained from these materials when exposed to X radiation. Particularly, the invention refers to the direct determination of carbon content in steel and alloys. According to the invention process, the inorganic materials are exposed to X radiation and the spectra are organized as a matrix and mathematically processed using chemometric tools properly selected.
