摘要
在血清样品中加入铂作基体改进剂,用1％Triton X-100稀释,在碱性介质下,用校正曲线法由等温平台石墨炉直接测定硒的含量,本法简单,快速,灵敏,稳定,可靠,特征质量为23.0pg/0.0044A.S.,变异系数为2.6—11.3％,回收率为94—104％.
The serum sample is diluted with 1% Triton X-100 and the selenium content is determined by stabilized temperature platform furnace in basic media using platinum as a matrix modifier. This method is rapid, convenient, and precise. The absolute sensitivity is 23.9pg/0.0044A.S., the coefficient of variation is 2.6-11.3%, and the recovery is 94-104%.
