The paper uses a prototype LIBS system using a diode pumped, passively Q-switched laser for the analysis of Rare Earth Elements in both solid (pellets) and liquid samples.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Eu 9.9000 (Calibration Curve Slope) 412.9400 466.36nm, 462.72nm 459.40nm, 420.51nm, 390.69nm, 382.97nm Univariate 250.0000-2500.0000 Analysis on pellet samples. The authors note several interferences to Al and Ca, that marred the performance. Detection limits in the range 10-39ppm obtained from the other peaks.
Yb 1.1500 (Calibration Curve Slope) 398.8000 N/A Univariate 100.0000-1000.0000 Analysis in Liquids. 369.42nm peak was considered, but showed strong self absorption
Eu 0.8500 (Calibration Curve Slope) 459.4000 466.19nm, 462.72nm Univariate 100.0000-1000.0000 Analysis in liquids. Detection limits of 1.05-1.54ppm obtained with the other peaks
