Résumé

Elemental LA-ICPMS mapping in continuous scanning mode gathers the counts generated upon laser ablation in line scanning mode. Acquisition of counts can be performed for each single laser pulse separately or by summing the counts of multiple laser pulses. Conventionally, pixels in an LA-ICPMS map are associated with spot-resolved single laser pulses (zero-dimensional, 0D), but also sub-pixel convolution strategies are in use, associated with one-dimensional (1D) or two-dimensional (2D) overlapping laser shots, and where possible followed by deblurring. The imaging quality of several 0D, 1D, and 2D LA-ICPMS strategies were compared for mapping of (ultra)low-concentration samples, both via computational and experimental approaches. The data presented will be helpful to make the right decision about the best possible LA-ICPMS mapping strategy for the highest image quality.
