摘要
The objective of this work was to study the homogeneity of the lot of the candidate certified reference material (CRM) composed of 16 polycyclic aromatic hydrocarbons (PAHs) in toluene, with the purpose of evaluating the degree of homogeneity among its units and within a same unit, evaluating the uncertainty contribution of homogeneity to the certified value. The method used complies with ISO Guide 30 series, being the ANOVA the statistical tool used to evaluate the variability among and within units. According to the statistical parameters, the homogeneity of the candidate PAHs CRM was confirmed for all substances with their respective property values.
