Summary

The performance characteristics of atomic absorption spectrometers used for determination of metal pollutants in water are set-up by legal metrology recommendations. As estimation of results is based on the instrumental comparisons between the signal provided by a known reference solution and the sample under investigation, the instrumental performance characteristics of the equipment are important to provide proper quality results. Some metrological characteristics of the instrument are presented and evaluated. From the measurement uncertainty evaluation of metal pollutant determination in water as well as from the metrological verification/calibration activities of atomic absorption spectrometers, some aspects affecting the quality of results are also identified and discussed.
