摘要
目的对测定乙基纤维素水分散体(B型)中乙基纤维素含量的2种方法进行比较分析。方法分别采用高效液相色谱法和气相色谱法测定乙基纤维素水分散体(B型)中乙基纤维素的含量。结果高效液相色谱法回收率为100.8%(RSD=1.3%,n=9),气相色谱法回收率为102.0%(RSD=2.6%,n=9),同批次样品2种方法的测定结果差异不大。结论为选择测定乙基纤维素水分散体(B型)中乙基纤维素含量提供了参考依据。
OBJECTIVE To compare two methods for the content determination of ethylcellulose in ethylcellulose aqueous dispersion type B. METHODS The content of ethylcellulose in ethylcellulose aqueous dispersion type B were determined by HPLC and GC respectively. RESULTS The average recovery of HPLC was 100.8% （RSD= 1.3%, n= 9）, and the average recovery of GC was 102.0% （RSD=2.6%, n=9）. The results by HPLC and GC show no significant difference. CONCLUSION This study helps control the quality of ethylcellulose aqueous dispersion type B with the proper method.
