SRM 1597 Complex Mixture of Polycyclic Aromatic Hydrocarbons from Coal Tar, originally issued in 1987, was recently reanalyzed and reissued as SRM 1597a with 34 certified, 46 reference, and 12 information concentrations (as mass fractions) for polycyclic aromatic hydrocarbons (PAHs) and polycyclic aromatic sulfur heterocycles (PASHs) including methyl-substituted PAHs and PASHs. The certified and reference concentrations (as mass fractions) were based on results of analyses of the coal tar material using multiple analytical techniques including gas chromatography/mass spectrometry on four different stationary phases and reversed-phase liquid chromatography. SRM 1597a is currently the most extensively characterized SRM for PAHs and PASHs.
煤焦油中多环芳烃的 SRM 1597 复杂混合物，最初于 1987 年发布，最近经过重新分析并以 SRM 1597a 的形式重新发布，其中包含 34 种经认证、46 种参考和 12 种信息浓度（以质量分数表示）的多环芳烃（PAHs）和多环芳烃硫杂环（PASHs），包括甲基取代的 PAHs 和 PASHs。认证和参考浓度（以质量分数表示）是基于使用多种分析技术对煤焦油材料进行分析的结果，包括在四种不同固定相上的气相色谱/质谱法和反相液相色谱法。SRM 1597a 是目前 PAHs 和 PASHs 特征描述最广泛的标准参考物质。
