己酸菌培养液中己酸含量的测定方法

Determination Methods of Caproic Acid Content in Caproate Bacteria Culture Fluid

介绍了己酸菌液中己酸含量的4种测定方法,即硫酸铜快速测定法、比色法、纸上层析法和直接进样毛细管柱气相色谱法,比较了它们的优缺点,直接进样毛细管柱气相色谱法快速、准确,但关键是要处理好样品。

Four methods including copper sulfate rapid determination, colorimetry, paper chromatographic method and direct sample injection capillary column gas chromatographic method to determine caproic acid content in caproate bacteria culture fluid were introduced in this paper and their advantages and disadvantages were contrasted. The results indicated that the application of direct sample injection capillary column gas chromatographic method could rapidly and accurately finish the determination. The key operation of this method was the proper preparation of the samples. (Tran. by YUE Yang)
