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.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Pd 20.0000 (Lowest Detected Concentrations) 340.4600 342.12 Univariate 0.0000-80.0000 The 340.46nm peak was chosen for this work as the 342.12nm peak had an interference from a hydroxide-ion emission band.
