This paper compares the performance of 3 Calibration-Free/Fundamental Parameters Analysis algorithms for the analysis of 6 Brass Standards. Brass was chosen as it is known to have strong self-absorption effects in the spectra. The algorithms compared are One Point Calibration, Calibration-Free Inverse method and Csigma analysis.
