Abstract:
The commercial LIBS instrumental results were compared to
previously optimized in-house LIBS systems and also to the alternative forensic
tools of LA-ICP-MS, mXRF, and SEM-EDS, which offer good analytical performance
but suffer from either very high costs and significant complexity (in the case
of LS-ICP-MS) or analytical limitations in the form of sample requirement and
relatively high detection limits (in the case of mXRF and SEM-EDS).
Although less mature than LA-ICP-MS, LIBS also shares the benefits
associated with laser ablation methods, with the added advantage of improved
speed, versatility, ease of operation, affordability, and portability.
This project shows that both LA-ICP-MS and LIBS are useful
analytical tools for the analysis of paper, inks, soil, and cotton. The results
have been presented in analytical chemistry and forensic science journals and
venues.
