Abstract

A device for analyzing at least one oxidizable molten metal using a LIBS technique, including: a LIBS analyzer; a mechanical rotary mechanism stirring a liquid bath of the at least one oxidizable molten metal, and including a central section, to be positioned above the liquid bath of the at least one oxidizable molten metal, including an internal cavity forming an analysis chamber, the central section including a first end connected to the LIBS analyzer, and a plurality of mechanical stirring paddles to be partially submerged in the liquid bath of the at least one oxidizable molten metal and that are connected to a second end of the central section opposite the first end of the central section, the LIBS analyzer configured to allow the surface of the at least one oxidizable molten metal located in the portion plumb with the internal cavity of the central portion to be analyzed.
