Determination of trace elements in nickel-base superalloys using a high-temperature hollow-cathode source

Abstract

A high-temperature hollow-cathode lamp, for the simultaneous determination of low boiling-point trace elements in nickel-base superalloys, has been developed in which very high intensities for the volatilised elements have been attained, with low spectral background and interferences. This work describes the calibration of the instrument and the superior performance achieved by the new design of the hollow-cathode lamp.
