The applicability of a mobile energy-dispersive micro X-ray fluorescence (μ-XRF) spectro-meter for the analysis of organochlorine-containing wood preservatives in art objects was tested. Information about the relative degree of contamination and the efficacy of detoxification measures with emulsive solvent systems can be gained using the intensity of the chlorine signals. μ-XRF technique combines the advantages of a high spatial resolution, as needed in studies of penetration profiles and transport processes of cut sections and the possibility to analyze larger areas in a relatively short time. The method allows a non-destructive determination of the degree of surface decontamination after cleaning treatments.
