摘要
采用毛细管柱气相色谱法研究了恒温和程序升温两种柱温模式对测试瘤胃液中挥发性脂肪酸含量结果的影响。研究结果表明,两种柱温模式均能很好的分离出瘤胃液中的乙酸、丙酸和丁酸,但程序升温模式测试单个样品的时间为8～9min,而恒温模式测试单个样品只需要6～6.5min,简便快捷。
To study the effect of the result of the VFA tested by capillary gas chromatography,using two different temperature（include constant temperature and temperature-rising procedure）patterns.The result indicated that acetic acid,propionic acid and butyric acid in rumen were all separated by two different tests completely.The test of temperature-rising procedure needs 8-9 min,however,the other one needs only 6-6.5 min.
