Abstract: | Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was applied for the sensitive multi-element analysis
of traces and ultra-traces in geological samples. In order to prepare homogeneous targets the powdered geological samples
were melted together with a lithium-borate mixture (90% Li2B4O7, 10% LiBO2) in a muffle furnace at 1050 °C. The quantification of the analysis results was carried out using the BCR-2G and BM standard
reference material (SRM). The experimentally determined relative sensitivity coefficients (RSC) for both SRMs vary between
0.2 and 3 for most of the elements, whereas the relative standard deviation (RSD) of the determination (N = 3) of the concentration
was 5–20%. The analysis results of LA-ICP-MS for various geological samples are in agreement with those of other methods.
