Abstract
A new method for the accurate determination of residual water in freeze-dried vaccines is described. Tests may be carried out on very small samples in sealed ampoules. The method is based on the adsorption of water from the vaccine with benzene and its estimation by gas chromatography. It appears that the residual water and total nitrogen content are important factors in the stability of the vaccine.
摘要
本文描述了一种准确测定冻干疫苗中残留水分的新方法。测试可在密封安瓿中的极少量样品上进行。该方法基于用苯吸附疫苗中的水分，并通过气相色谱法进行估算。看来残留水分和总氮含量是疫苗稳定性的重要因素。
