U and Eu were analysed in glass samples using both 532nm and 355nm lasers. The authors report emission intensities ~30times stronger for 355nm vs 532nm laser. The laser was focused 7mm behind the sample surface to prevent above surface breakdown. Despite good results, analysis of a sample containing 462ppm U could not be completed due to inteferences from Y and Gd
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Eu 4.2000 (Calibration Curve Slope) 459.4030 N/A Univariate 2000.0000-50000.0000 Calibration curve shows quite strong self absorption above 10000ppm
U 150.0000 (Calibration Curve Slope) 358.4880 356.659nm Univariate 2000.0000-50000.0000 Calibration curve was ratioed to 299.731nm Ca Peak. Calibration curve is linear up to 10000ppm but shows self absorption at higher concentrations.
