Dioxin analysis

The research group

The department Product Safety and Analysis has long-term experience in identification and quantitation of contaminants in trace levels especially for the analysis of polychlorinated dioxins and furans (PCDD/F) in pulp and paper production. Our research group works on this field since 1989. The group successfully took part in the round robins PCDD/F in sewage sludge "Bundesweite Qualitätsprüfung 1994 der Universität Tübingen für PCDD/F in Klärschlamm", "Bundesweite Qualitätsprüfung 1999 der GAM für PCDD/F in Klärschlamm" and in soil "Bundesweite Qualitätsprüfung 1997 für PCDD/F in Böden". The IVV has adopted a quality assurance system according to DIN EN ISO/IEC 17025. In the field of migration testing the laboratory is accredited since 1996. Enlargement of the accredited area including the dioxin laboratory was done in 2000. (DAP-PL-3909.00)

The research group owns 3 laboratories for the sample preparation. Conventional chromatographic methods of sample preparation and cleanup are used as well as SEC. Analyses are done by HRGC/HRMS. The instruments used are Finnigan MAT 95. They are dedicated to dioxin analyses and reaches absolute detection limits of approximately 10 femtogramm. For higher contaminated samples there are also low resolution MS available.
