| Description | Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) offers possibilities of elemental mapping different types of materials which includes metallic, biological, geological samples. Its advantage consists in sufficient lateral resolution (in order of tens um) and low detection limits (in range of ones mg/kg). In presented work, the elemental mapping granitic sample originated from Bohemian massif is presented. New analytical software – Laser Ablation Tool was used for data treatment and its utilization for elemental map creation is described. For quantification purposes two quantification methods were utilized - total sum of signals of isotopes and external calibration with internal standard normalization. We discuss their advantages and drawbacks for quantification purposes of heterogeneous samples. |
