A separation‐oriented derivatizationmethod using a specific fluorous affinity between perfluoroalkyl‐containing compounds was applied to selectiveliquidchromatography/tandemmass spectrometric (LC/MS/MS) analysis of sialyl oligosaccharides. The perfluoroalkyl‐labeled sialyl oligosaccharides could be selectively retained on an LC column with the perfluoroalkyl‐modified stationary phase and effectively
在含全氟烷基的化合物之间使用特定的氟亲和力的分离导向衍生化方法被用于唾液酸低聚糖的选择性液相色谱/串联质谱分析(LC / MS / MS)。全氟烷基标记的唾液酸寡糖可以通过全氟烷基改性的固定相选择性地保留在LC色谱柱上,并与非衍生化物种有效区分开。
