LIBS is used to detect palladium nanoparticles suspended in the cathode water from fuel cells to monitor the degradation of the cells. The Authors used the conditional analysis techniques usually used in aerosol analysis to determine which spectra to include in the Pd determination. To improve the liquid analysis, a jet was used to simplify the focussing conditions. In addition, a coagulant was added which improved the spectra hit ratio. |
