LIBS type measuring head for the analysis of compounds in a dusty environment and / or at elevated temperature

摘要

Measuring installation provided with an analysis head by laser-plasma spectroscopy of the LIBS type, by Laser-Induced Breakdown Spectroscopy, intended for the chemical analysis of a high temperature bath in a dusty environment, and provided with a cooling device and of protection against fumes and dusts, which comprises a base of horizontal preference (1) that supports a watertight drawer (2) that contains a laser and optics to be protected, the indicated installation being characterized by comprising cooling means that act as a screen to the radiation emanating from the bath and ensuring the evacuation of heat transmitted by conduction, the indicated cooling means comprising a water cooling circuit (1A) located at the base of horizontal preference (1) and at least four water radiators (5) forming an enclosure around the sealed drawer (2) and pivotally mounted on the base (1) by means of b isagras (5A) and why the base is located above the bath to be analyzed.
