摘要
介绍甲醇中1,2-二氯乙烷溶液标准样品的研制方法。本溶液标准样品采用称量法制备,气相色谱/质谱法进行均匀性检验和稳定性监测,以配制值为标准值,并评估其不确定度。研究结果表明,甲醇中1,2-二氯乙烷溶液标准样品均匀性和稳定性良好,量值准确,可用于环境监测和科学研究工作。
The development technique of the certified reference material of 1,2-Dichloroethane in methanol was pre- sented,the homogeneity and stability were tested by GC/MSD.The results showed that the certified reference materi- als are homogeneity,stable and accurate.It may be used in the environmental monitoring and scientific research.
