Analysis of nickel alloys by ICP-MS with laser ablation
Currently nickel alloys are widely used in modern aviation industry and engine building. They are made of critical parts with thermal and power load. An important task is to control the chemical composition of nickel alloys, especially the content of trace. In this work determination of B, Si, P, Mn, Fe, Cu, As, Se, Sn, Sb, Pb and Bi in the certified standard samples of nickel alloys by a mass spectrometry method with inductively coupled plasma and laser ablation (ICP-MS-LA). The technique of preparation of test for the analysis is given. The results are compared with the results of the analysis of the classical method of ICP-MS. The detection limits are as follows: the range of detectable concentrations 0,00002–2,2% (by weight), relative standard deviation is less than 0,07.
