Mineral Analysis with Handheld LIBS
Author(s)Don Sackett, Brendan Connors
This paper describes a handheld LIBS device that analyzes major elements, transition and heavy metals in geochemical samples. A breakthrough of this technique is the ability to analyze very low atomic number elements including H, Li, Be, B, C, F, Na and others never before measured in the field with a handheld analyzer.

Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
Atomic Perspectives
This Atomic Perspectives column explains how high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS-GFMAS) quantifies extractable organic fluorine (EOF) as a PFAS sum parameter, complementing LC-MS/MS target analysis, with applications to German river sediments, bean plants, and fluorinated polymer sealing materials.
