摘要:

挥发性脂肪酸(VFA)是厌氧发酵反应运行的重要控制指标,确定一种准确、精密、简便、快捷的测试方法十分必要.实验采用GC-122气相色谱仪,N2000色谱工作站,有机担体402为填料,FID作为检测器,在柱温200℃,载气(N2)流量52.0 mL/min条件下对经过甲酸预处理后厌氧发酵液样品中的VFA进行了测定.结果表明,该方法分离效果好,各组分的回收率在94%～108%之间,变异系数小于3%,重复性好,且测试时间较短.

Abstract:

Volatile fatty acids (VFA) are important control indicators for anaerobic fermentation reactions, and it is necessary to determine an accurate, precise, simple and fast test method. In the experiment, GC-122 gas chromatograph, N2000 chromatography workstation, organic carrier 402 as packing material, and FID as detector were used to determine the VFA in the anaerobic fermentation broth sample after formic acid pretreatment under the conditions of column temperature of 200°C and carrier gas (N2) flow rate of 52.0 mL/min. The results show that the separation effect of this method is good, the recovery rate of each component is between 94%~108%, the coefficient of variation is less than 3%, the repeatability is good, and the test time is short.
