This paper explores the use of a LIBS rig suitable for use in the field with a focus on low power requirements and small size. Soil samples were prepared by adding solutions of the elements to the same base soil, then dried at 40C, ground and pressed into pellets
Element Detection Limit (ppm) Wavelength (nm) Other Wavelengths (nm) Calibration Method Calibration Range (ppm) Notes
Pb 8000.0000 (Stated) 220.3500 N/A Univariate Calibration 3500.0000-107100.0000 The authors were not able to use the more sensitive 405.78nm line due to spectral interferences. Depth profiling of the lead concentration was also possible with this equipment. This paper also includes some double pulse LIB results. This work was also repeated with a non-gated detector, with similar performance.
