Improvement of analytical characteristics for the determination of impurities in high temperature nickel alloys using ICP-MS

Yakimovitch P.V., Alekseev A.V.
Abstract

In this work, the determination of P, As, Se, Cd, Cu, Zn, Te, Sb in samples of complex alloy nickel alloys by inductively coupled plasma mass spectrometry (ICP-MS) was carried out. The technique of dissolving the sample and preparing it for analysis. Applied different techniques for elimination of spectral interferences and improve sensitivity definitions: reaction-collision cell and mathematical correction. Range of determined concentrations were 0,00001–0,087% by weight, relative standard deviation not greater than 0,05.

Keywords
mass spectrometry with inductively coupled plasma (ICP-MS), nickel alloys, de-termination of impurities, microwave sample preparation.
