研究了一种按Y=2.05×1.4~1指数程序涂渍的气相色谱柱快速测定菜籽汕中脂肪酸的方法。该法所需的时间比均匀填充柱大大缩短,且指数程序涂渍色谱柱的柱效、塔板高度及分离度均优于均匀柱。
A method for rapid determination of fatty acids in rapeseed Shantou by GC with Y = 2.05 × 1.4-1 index program was studied. The time required by the method is much shorter than that of uniform packed column, and the column efficiency of column coated with exponential program is better than that of uniform column.
