- •
A new method based on neutron activation for the multi-elemental characterization of atmospheric dust entrapped in polar ice cores is proposed.
- •
37 elements were quantified in μg size dust samples with detection limits ranging from 10−13 to 10−6 g.
- •
A low background approach and a clean analytical protocol improved INAA performances to unprecedented levels for multi-elemental analyses.
