采用HPLC分析了聚甘油的组成，其线性聚甘油及环状聚甘油的保留时间的对数均与其相对分子质量呈线性正相关，线性方程分别为lg tR=0.0013 M+2.5047和lg　tR=0.0018 M+2.3220.用化学法和HPLC两种方法测定聚甘油样品中甘油的含量，结果基本一致.

The compositions of the polyglycerols were analyzed by HPLC on the YWGNH2 Column in this paper. Each logarithm of retention time (tR) of the linear polyglycerol and the cyclic polyglycerol v.s. its molecular weight is linear correlative. The linear equation is lg tR=0.0013 M+2.5047 and lg tR=0.0018 M+2.3220 respectively. The contents of the glycerol in the polyglycerols determined by the chemical method and HPLC were compared.
