Direct Elemental Analyses of Ink on Paper by Laser Ablation ICP-MS (PDF)
The CETAC LSX-500 Laser Ablation System is suitable for trace element microanalysis of virtually any solid sample. Here CETAC Technologies describes the use of the LSX-500 for elemental analysis of inks on paper. For more information, visit the company's website at www.cetac.com.
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.
The following articles are the most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during the month of September 2026. Nine articles are individually ranked here by DOI page views; the third-highest entry (186 views) was recorded against the bare journal-level DOI rather than an individual article and is therefore not attributable to a single manuscript.
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.
