| The authors measure the concentration of rare earths (Eu and Yb) directly in solution. Prior to calibration curve construction, a study of the effect of delay and laser power on peak intensity were made to determine the best conditions. | |||||
| Element | Detection Limit (ppm) | Wavelength (nm) | Other Wavelengths (nm) | Calibration Method | Calibration Range (ppm) | Notes |
|---|---|---|---|---|---|---|
| Yb | 156.0000 (Calibration Curve Slope) | 398.7900 | N/A | Univariate | 500.0000-10000.0000 | Element in solution. Only one line was detected. |
| Eu | 256.0000 (Calibration Curve Slope) | 459.4000 | 462.72nm, 466.18nm | Univariate | 500.0000-10000.0000 | Better results were obtained using the ionic lines, but in all 3 neutral lines were also tested. |
| Eu | 209.0000 (Calibration Curve Slope) | 420.5000 | 381.96nm, 390.71nm, 393.04nm, 397.19nm 412.97nm, 443.55nm | Univariate | 500.0000-10000.0000 | Best performance was using the ionic line. In all 7 ionic lines were tested for best performance |
