T1 - The Problem of Large Samples - The Analysis of Electronic Waste Material T2 - Proceedings / EMC 2005, European Metaalurgical Conference N2 - Large-volume instrumental photon and neutron activation analysis (IPAA resp. INAA) was used for investigation of shredded electronic waste material. Sample masses from 1 to 150 grams were analysed to obtain an estimate of the minimum sample size to be taken to achieve a representativeness of the results which is satisfactory for a defined investigation task. Furthermore, the influence of irradiation and measurement parameters upon the quality of the analytical results were studied. Finally, the analytical data obtained from IPAA and instrumental neutron activation analysis (INAA), both carried out in a large-volume mode, were compared. Values within the limits of satisfactory agreement were found only partially. Analytical process control using on-site X-ray fluorescence analysis performed during recycling of electronic waste is currently under development.
