摘要
在生产实践中发现,使用721型分光光度计———比色法测定己酸菌液中己酸含量的方法不够准确。通过采用不同方法测定对比,确定了通过蒸馏己酸菌液,然后用色谱法测定其中己酸的含量的方法。该法分析准确度高,避免了比色法的误差。(陶然)
It was found in practice that the accuracy of the determination of the content of caproic acid in caproic acid bacteria solu-tion by721type spectrophotometer—colorimetry was unsatisfactory.Different determination methods were compared and the best one was chromatography after the distillation of caproic acid bacteria solution.The method was of high accuracy and could effectively avoid the errors.(Tran.by YUE Yang)
