A Method for Estimating the Certified Value Uncertainty of a Multicomponent Reference Material
Reference materials, 2019 This paper presents the results of a series of studies aimed at investigating the reference material (RM) of a multicomponent solution. An algorithm for estimating the uncertainty induced by the chemical element content in the RM is proposed taking into account the mass of the measurand in each component of the mixture. The results calculated according
