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
