Trace element maps give unique insight to homogeneity, enrichment, and spatial distribution of elements in solid samples. Depending on the sample type, we can gain a wealth of information from sample maps beyond what is available from single or multiple spot analyses or single lines/rasters.
Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) provides high spatial lateral resolution and can be used to construct trace element maps with minimal destruction of the sample. A study using LA-ICP-MS completed by Teledyne CETAC, Arkansas Biosciences Institute and Arkansas State University compiled and interpreted elemental maps for three distinct sample types: banded iron formation (BIF), human teeth and fish otolith.
