动态浊度法定量测定血液保存液Ⅰ中细菌内毒素含量

Determination of the bacterial endotoxin concentration in blood preservation liquid I by dynamic turbidity

目的:应用动态浊度法定量检测血液保存液Ⅰ中细菌内毒素含量。方法:采用《中国药典》2005年版附录细菌内毒素定量检查法。结果:将血液保存液Ⅰ进行1∶40稀释后可排除干扰,回收率在50%～200%,无干扰作用。结论:应用动态浊度法定量测定血液保存液Ⅰ中的细菌内毒素是可行的。

Objective：To determine the bacterial endotoxin concentration in blood preservation liquid I by dynamic turbidity. Methods：To use the bacterial endotoxin quantitative inspection method in appendix of China Pharmacopoeia 2005 version. Results：Remove interference after diluting the blood preservation liquid I at ratio of 1∶40,recovery is 50～200%. Conclusion：To use dynamic turbidity to determine the bacterial endotoxin in blood preservation liquid I is feasible.
