摘　　要：介绍了甲醇/二氯甲烷(V(甲醇):V(二氯甲烷)=1:1)中苯并[a]芘溶液标准样品的研制过程。该标准样品采用称量法制备,用气相色谱-质谱法进行均匀性检验和稳定性监测,对不确定度来源进行了全面评估,并与国际同类标准样品进行了量值比对分析。结果表明,该溶液标准样品均匀性和稳定性良好,量值准确可靠,可用于环境监测和科学研究工作。The development of a certified reference material of benzo[ a] pyrene in methanol/dichloromethane. The certified reference material was prepared by weighing method, and its homogeneity and stability were tested by GC-MS. The results showed that the certified standard reference material had good homogeneity, stability and accuracy, and it can be used for environmental monitoring and research.
