The authors use CF-LIBS to analyse 3 fragments of the Kosice Meteorite. Results are compared to ICP-OES. Electron density was determined from the H(alpha) line width. Lines with high probability of self-absorption were removed from the analysis where possible, however in the case of Na and Al this was not possible, leading to larger uncertainties in the results.
