由于Ｃ１８色谱柱品牌规格和填料粒径等不同，用相同流动相对分离差异很大。我们用ＩｎｅｒｔｓｉｌＯＤＳ－３（４．６ｍｍ×２５０ｍｍ，５μｍ）柱，按国家标准方法［１］的甲醇与０．０２ｍｏｌ／Ｌ醋酸铵作流动相，各种配比，对糖精、苯甲酸、山梨酸分离都不理想，特...
Due to the different brand specifications and particle size of C18 columns, the separation is quite different with the same flow. We use InertsilODS-3 (4.6mm × 250mm, 5μm) column, according to the national standard method [1] of methanol and 0.02mol / L ammonium acetate as the mobile phase, various ratios of saccharin, benzoic acid, Separation is not ideal, special ...
