Liquids for analysis were dried onto pellets of CaCO3 and Graphite. In general, the graphite pellets yielded lower detection limits.
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Cs 600.0000 (Smallest Peak Observed) 852.1000 N/A Univariate 600.0000-10000.0000 No LIBS peaks were detected for Cs on CaCO3 pellets, but detection limit of 600pm observed on the graphite pellet
Ce 100.0000 (Smallest Peak Observed) 305.8000 303 Univariate 100.0000-10000.0000 Significantly better detection limits for analysis of liquid dried onto graphite pellets compared to CaCO3. Authors attribute this to better laser absorption leading to more energy transmitted into the plasma
Sr 10.0000 (Smallest Peak Observed) None N/A Univariate 10.0000-1000.0000 Not the main focus of this paper. Obtained by drying solution onto CaCO3 pellet
