Description

This study presents the uncertainty estimate for characterization, study of homogeneity and stability study obtained in the preparation of a reference material for the determination of total mercury in fish fresh muscle tissue for proficiency testing. The test results for stability were obtained by linear regression and to homogeneity study was obtained by ANOVA-one way showed that the material is homogeneous and stable. The value of total mercury concentration with expanded uncertainty for the material was 0,294 ± 0,089 μg g-. (author)
