| 摘 要： | 本文使用气-质联用仪对微生物降解原油发酵液中低分子量有机酸进行测定。采用水蒸汽蒸发法蒸出发酵液中低分子量有机酸，从而使其与样品中大量的无机盐和表面活性剂分离，浓缩后直接进样。该方法简单直接，可以减少有机酸的损失。

| Abstract: | In this paper, GC - MC is used to determine the organic acids with low molecular weight produced by the microbial degradation of crude oil zymotic fluid. Wet distillation is applied to distill the organic acids with low molecular weight in the zymotic fluid, thus separating them from the large amount of inorganic salts and surfactants in the samples. Direct sampling is conducted after the concentration of the distilled acids. This method features great simplicity, directness, and little loss of organic acids. |
