Propagation of uncertainty in multi-matrix analysis by GD-OES

Author affiliations

Abstract

Propagation of uncertainty was analysed in multi-matrix calibrations by GD-OES and a formalism was developed to calculate uncertainties of the calibration parameters, sputter factors and the predicted concentrations in the standard model. This formalism is intended for evaluation of the analytical performance of different experimental setups and as a basis for further developments of the calibration model. In this work, it was applied to a multi-matrix calibration covering a wide range of mostly nickel-based alloys. Evidence was found that deviations from the standard model exist in that calibration. Typical levels of uncertainty to be expected in the multi-matrix analysis by GD-OES are presented.
