摘要
介绍了低浊度值聚苯乙烯乳胶粒子浊度标准液的制备、定值及使用方法。该低浊度值聚苯乙烯乳胶粒子浊度标准液符合国际标准７０２７的要求 ,具有良好的均匀性和稳定性 ,定值准确可靠 ,浊度标准值为１００ＮＴＵ ;定值不确定度为４ % (ｋ＝２),在低浊度范围可替代Ｆｏｒｍａｚｉｎｅ浊度标准物质。
The methods of preparation,certification and use for polystyene particles of lowturbidity standard solution are introduced.The lowturbidity standard solution is up to the international standard7027.The homogeneity and stability is qualified,the turbidity stan-dard value is100NTUand the uncertainty of certification is4%(k=2).The low turbidity standard solution will substitute for formazine turbidity standard solution within the range of lowturbidity.
