Non-traceable calibration is a source of disagreement between analytical results from different laboratories, particularly in the field of organic trace contaminants in food (for example milk) or environmental samples (for example fly ash, soils, sediments). In order to eliminate sources of calibration errors, the BCR programme has supported research on the production of guaranteed and certified calibration solutions of dioxins, chlorinated biphenyls and polycyclic aromatic hydrocrbons. A feasibility study was necessary to establish the metrological validity of the gravimetric preparation of such calibrants, as well as the absence of systematic error in the ampouling procedure of the solutions. This report describes the methodology followed and the experimental results obtained for dioxin solutions.
