Developments of Environmental Certified Reference Material from the Brazilian Metrology Institute to Support National Traceability
نویسندگان
چکیده
This paper aims to present the developments performed by the Brazilian Metrology Institute (NMI) – Inmetro, considering the environmental demand. Inmetro addresses great part of its activities to the study of the traceability transference based on production and dissemination of certified reference material (CRM) of different areas in chemistry. It will be presented results from certification of the following reference materials developed: BTEX and PAH in solution, besides automotive emission gas mixtures and bioethanol. So, the achievements made are the growth in developing CRM, in order to support the needs of the national industry and to disseminate traceability among the society.

متن کاملCharacterization of certified reference material for the quantification of water in bioethanol.
The National Metrology Institute of Japan has issued a certified reference material of bioethanol (NMIJ CRM 8301-a) for the quantification of water, methanol, sulfur, and copper. This paper presents technical details for the characterization of the water in NMIJ CRM 8301-a. The characterization was performed using coulometric and volumetric Karl-Fischer (KF) titrations. To reduce moisture absor...
