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). Witryna4 sty 2024 · The impurity distribution is the result of the parallel force balance which in the stationary form can be written as [29, 30]: Where −∇ n I T i represents the pressure gradient, S I,fr is the friction force due to the main ions, S I,th is the thermal force and eZn I ∇ II φ the electric force.
