Characterization of metal-containing nanoparticles in tattoo ink using AF4 coupled with MALS and ICP-MS
This study demonstrates the excellent suitability of AF4-MALS-ICP-MS for the comprehensive characterization of tattoo inks. Besides the particle size distributions obtained from the MALS data, ICP-MS additionally allows statements on the elemental distributions of various metals as a function of the respective particle sizes, providing valuable insight into the composition of the inks.
