摘要
本文介绍了甲醇中苯并(a)芘标准物质的研制过程。对原料的纯度进行了定量测定,对浓度范围、溶剂、安瓿材质及影响其稳定性的因素做了选择实验,并介绍了该标准物质的均匀性、稳定性检验以及定值的方法和结果。
This paper describes the study and preparation of certified reference material benzo(a)pyrene in methanol,including the purity analysis of the material and the choice of analytical conditions such as concentration range,solvents,ampoule material and others which affect the stability of the material.Measurement results on its homogeneity,stability and certified value are also given.
