| 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 |
