一、引言: 泥煤蜡中C_(29)—C_(32)脂肪酸的分析虽有过文献报导,但却无定量结果。毛细管色谱具有快速高效特点,适用于高碳脂肪酸分析。从近期文献报导中看来,对高黏度的固定液(如SE—30等)用汞塞法动态涂渍其柱效较高,且较静态法简易快速。为此,我们将大连405担体经酸洗制成SCOT柱,并用汞塞法进行动态涂渍SE—30固定液,效果良好。对廿四脂肪酸甲酯在柱长为25米×φ0.45毫米的SE—30柱上其有效塔片数 I. Introduction: Analysis of C_ (29) -C_ (32) fatty acids in peat wax has been reported in the literature, but there are no quantitative results. Capillary chromatography has the characteristics of fast and efficient, suitable for high-carbon fatty acid analysis. It seems from the recent literature that the high viscosity of the fixative (such as SE-30, etc.) with mercury plug dynamic coating method of its higher efficiency, and relatively simple and quick method of static. To this end, we will Dalian 405 body was acid washed SCOT column, and the use of mercury plug dynamic SE-30 fixative solution, the effect is good. Twenty four fatty acid methyl ester in the column length of 25 m × φ0.45 mm SE-30 column on the number of effective column
