【 摘 要 】
Initially, for acquiring experience in determining the purity of the dichromate by coulometry, a bilateral comparison between the national metrology institutes (NMIs) from Brazil and Russia was carried out. Next, to evaluate the comparability of the measurement results among the NMIs that use high-precison constant-current coulometry for certifying reference materials (RMs) of pure compounds, National Institute of Metrology, Quality and Technology (Inmetro) participated in a
