Abstract Scope |
It is imperative to comprehensively understand the chemistry of molten salts for designing robustly engineered systems in the next generation in solar and nuclear power applications. To this end, significant strides have been made in the molten salt research community to develop electrochemical sensors to monitor online various chemical species of impurities and corrosion products. However, independent verification of dissolved analyte quantities in the molten salt by conventional techniques such as Inductively Coupled Plasma mass spectrometry and optical emissions spectroscopy severely limits the turnaround time for sensor calibration due to the necessity of intermediate gravimetry and acid digestion analytical preparation steps. Acid digestion is also highly specific to analyte and chemical species, further encumbering the analysis of multiple chemical species within the same salt sample. We present a solution to these problems by a batch-sampling LIBS process to simultaneously quantify multiple dissolved analytes in salts at room temperature per sample. |
