Abstract The application of factor analysis in EDXRF as a method for evaluation of elemental concentrations and calculation of net peak areas is demonstrated in two examples. A quantitative PCR-analysis of sulphur interfered with by molybdenum could be performed by using the XRF-spectra as input with a standard error of analysis (SEA) below 0.2 mg/g for aqueous and 3.6 mg/g for solid samples. By using PCR-predicted net peak areas as input for the empirical evaluation method developed by Lucas-Tooth and Price, the SEA for solid samples could be decreased to 2.3 mg/g. The comparison of PCR to PLS showed no significant difference.
