Beskrivelse
The use of certified reference materials is an alternative that laboratories have to guarantee the quality of their analyses, which is why many of them have been investing in the production of their own in-house reference materials. This paper presents the application of an interlaboratory test for the certification of Fe, Ca, Si, Ni, Na, P and V in a sample of carbon electrodes, a candidate for in-house reference material, from an aluminum industry in Brazil.
