Certified reference material (CRM) plays a vital role for quality control assurance in environmental analysis, because the quality of data arising from measurements has crucial importance. This article presents the results from studies carried out for certification of a candidate reference material composed by sixteen polycyclic aromatic hydrocarbons (PAHs) dissolved in toluene (naphthalene, acenaphthylene, acenaphtene, fluorene, anthracene, phenanthrene, fluoranthene, chrysene, benzo[a… Expand
