Analysis of Nickel Metal Alloys using LA-ICP-MS Application Note · PlasmaQuant MS
Introduction
The coupling of ICP-MS, mass spectrometry with inductively coupled plasma and laser ablation allows the characterization of solid samples without digestion or other sample preparation procedures. This work evaluates the suitability of this technique for the characterization of trace element concentrations in metal alloys.
The quality control of metal alloys with laser ablation requires large spot sizes to quantify the average trace element concentration in the bulk sample. The aim of this analysis is the method development for the characterization of trace element concentrations in alloys using LA-ICP-MS with focus on calibration strategies.
The analysis was concentrated on elements that require lowest possible detection limits that for now cannot be ensured with complementary techniques. Main focus was put on elements like As, Se, Ag, Sb, Te, Tl, Pb, Bi as well as Ca and Mg. Additional elements were included to show the capability of the method for a simultaneous analysis of more elements.
