Laser ablation inductively coupled plasma mass spectrometry as a tool for elemental mapping heterogeneous sample

Popis výsledku v původním jazyce

Nowadays, LA-ICP-MS represents powerful tool for determination of minor and trace elements in geological samples. However, the problem appears if some elemental map of heterogeneous geological samples should be created. The problem consists in two facts.The first one, the ablation rate of each phase of the sample differs. This problem could be easily solved using internal standard. However, the second problem arises now. We analyze heterogeneous samples hence each phase can have different internal standard and its content may also vary. In presented work we describe the possibility of elemental mapping heterogeneous geological samples using LA-ICP-MS. For this purpose we used setup consists of laser ablation system UP213 (NewWave, USA) operating at wavelength of 213 nm and quadrupole ICP-MS Agilent 7500ce (Agilent, Japan). The presented elemental maps were obtained by laser ablation of granitoids from Bohemian massif what represents sufficient heterogeneous samples (mica, quartz, feld
