Sparge Sampling of Molten Salts for Online Monitoring via Laser-Induced Breakdown Spectroscopy.

ABSTRACT: A method was developed to sample molten salts by sparging to generate and transport aerosols to an isolated instrument for compositional analysis by laser-induced breakdown spectroscopy (LIBS). Real-time monitoring of molten salt composition is critical to developing molten salt nuclear reactors, which offer enhanced safety and efficiency. In this article, the sparge sampling method is described and compared with sampling using a Collison nebulizer. The size distribution and transport of aerosols produced from molten eutectic NaNO₃-KNO₃ salt were compared for multiple gas flow rates (75-1200 mL min^-1) and transport distances (0.68-2.61 m). Both methods produced aerosols ranging from 0.5 to 5.0 μm determined using a cascade impactor. Aerosols were effectivel
