原始语种摘要: Abstract(#br)This study evaluates the possibilities and limitations of infrared laser ablation – inductively coupled plasma mass spectrometry, using 43 Ca as internal standard and the silicate glass reference materials NIST 610/612 as calibration standards, for quantifying the spatiotemporal variations of Mg, Mn, Sr, Ba and Pb in the calcite layer of Mytilus edulis shells. It demonstrates that the ablation behaviour of Ca relative to those of the analytes is dependent on the ablation time and substrate matrix (inorganic and biogenic calcite versus NIST 610/612); however, for ablation times ≤80s, internal standardization with Ca improves precision to <10% relative standard deviation (RSD) for all tested substrates. Variations in the Ca distribution in the studied shells...
