ESTIMATE OF UNCERTAINTY OF MEASUREMENT IN THE DETERMINATION OF METHYLMERCURY IN FISH SAMPLES BY FIA-CV-AAS

摘要

The uncertainty for methylmercury determination in fish samples by cold vapor atomic absorption spectrometry technique was estimated based in the guide for quantifying uncertainty in analytical measurement of EURACHEM and ISO to the expression of uncertainty in measurement. The expanded uncertainty (9,5%) was obtained with 95% confidence level (k = 2).
