ACQUITY UPLC CSH氟苯基色谱柱对位置异构体、卤代化合物和极性化合物具有优异选择性。部分原因在于多种保留机理的综合效果，包括偶极-偶极作用、氢键作用、芳香性(π-π)作用和疏水作用。但由于带电表面颗粒[CSH]的独特化学特性，与传统PFP键合固定相相比，CSH氟苯基色谱柱可增强对酸性化合物的保留。
采用超高压液相色谱-电喷雾串联四极杆质谱建立了酱油、醋和可乐中的氟乙酸的快速检测技术,为相关中毒事件的样本分析提供方法学依据。方法食品样本用水稀释后经C18固相萃取小柱净化, Waters ACQUITY UPLC CSH Fluoro-Phenyl色谱柱分离,以0.1%乙酸水和乙腈溶液为流动相梯度洗脱,最后用液相色谱-串联四极杆质谱仪在负离子MRM模式下测定。结果目标化合物在2.0~1000μg/L范围内线性良好,相关系数r2大于0.99。以酱油、醋和可乐为加标基质,在50、100、200μg/kg三个加标水平下氟乙酸的平均回收率为82.4%~107.1%,相对标准偏差小于20%,方法的检出限为10μg/kg,定量限为25μg/kg。结论该方法操作快速简单、灵敏度和重现性较好。
