Impurity distribution
Witryna19 mar 2024 · The distribution of major and a few minor elements were determined by micro X-ray fluorescence (µXRF), hydrogen concentrations by polarized and unpolarized Fourier-transform infrared spectroscopy (FTIR), and minor, trace/ultra-trace element concentrations by laser ablation inductively coupled plasma mass spectrometry (LA … Witryna30 this new approach was transferred to ice core analysis with LA-ICP-MS, now offering to study the impurity distribution in ice cores in 2D. First results clearly demonstrated a close connection between grain boundaries and high-resolution LA-ICP-MS signals, which became particularly evident for the example of sodium (Bohleber et al., 2024).
