摘要
对新研制的水质色度环境标准样品进行了稳定性检测、均匀性检验及定值,确立了水质色度环境标准样品的制备、检验与定值程序。研究结果表明,新研制的水质色度标准样品的均匀性良好,至少在两年的时间内稳定,定值方法可靠,量值准确。
Through stability and homogeneity assessment and certification, we have developed the preparation, test and certification procedure of a new water quality-color cezrtified reference material. The research resuh has showed that the water quality-color certified reference material has a well homogeneity and is stable at least for two years with trustable certified concentration value.
