摘要: 冰冻干燥红细胞样品中的含水量是影响冻干红细胞再水化后功能的重要指标.冻干红细胞聚集成团,水分和样品混杂在一起,难于被充分分离出来和进行准确检测.我们用和水混溶的丙酮作溶剂,把冻干红细胞样品中的水置换出来,按照标准加入法用氢谱积分准确测定其中的水信号.该方法方便快捷,准确可靠.

Abstract: The content of water in freezed-dried red bolld cells, which influence on the function of red blood cells after rehydration is an important specification.It is diffiant to separate and determine precisely because water and samples were mixed and incorporated. The content of water was gained by routine proton NMR integration combined with the method of standard addition, after water in samples was completely absorbed by d6-acetone, which is soluble in water in all proportions. The result showed that this approach is simple, easy and accurate.
