| In this work, the authors use the novel method of Hydride Generation to introduce the solutions of interest to LIBS analysis. In addition, analysis is performed in a mixture of Ar and H2 gases [H from the Hydride Generation process]. The presence of H2 is noted to reduce the plasma temperature. | |||||
