Reference materials and certified reference materials for spectrometry in Romania

Fresenius' Journal of Analytical Chemistry, 2001
Several reference materials (RMs) and certified reference materials (CRMs) are widely used in Romania as measurement standards in different spectrochemical measurements. Among them, single element standard solution certified for their mass concentration play a key role in ensuring the required traceability of results expressed in this measurement unit.
