Description	Data on elemental fractionation of alkali elements during laser ablation ICP-MS analysis of reference glasses (NIST-610, BCR-2G, alkali-doped andesite glasses) and crystalline albite are reported. LA ICP-MS and SIMS were used to determine changes in sample composition before and after laser interaction with the samples. The rate of fractionation varies for different sample matrices and for different alkali elements in the same matrix. Analyses suggest a matrix dependent fractionation of alkali elements for different particle size fractions in the ablated aerosol. The extent of fractionation varies for different alkali elements and is independent of their ionic radii. Depth profiling into the bottom of laser craters showed laser ablation-induced chemical changes in the sample that involved alkali elements and major matrix elements including Si and Ca. This suggests that a combination of thermally-driven diffusion and size-dependent particle fractionation are responsible for the observed fractionation.
