Detailed knowledge about the principles of the techniques as well as knowledge of the whole analytical process are necessary to 'produce' measurement results of adequately high quality.According to the conclusions resulting from IEMM's Ineternational measurement program (IMEP) rounds, IMEP-6 and IMEP-9 where the participating laboratories used four different spectroscopis techniques, that is not always the case: more than 50% of the spectroscopic results with their stated uncertainties do not overlap with the uncertainty range of the certified/assigned reference value. It is obvious that the analytical community must put greater effort n the establishment of a better common metrological basis for measurementsTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaSlovensko kemijsko društvo
