疏水反相保留机理、硅胶颗粒
与CORTECS，CSH和BEH颗粒相比，ACQUITY UPLC HSS色谱柱为极性与非极性分析物提供更理想、更平衡的保留效果。经过工艺优化的硅胶颗粒，其机械强度与稳定性更能耐受。UPLC系统操作压力。5种差异较大的键合相，提供更宽泛的选择空间，除了传统的疏水反相保留机理之外，还有偶极-偶极、芳香与氢键相互作用。
ACQUITY UPLC HSS C18 SB色谱柱是一种未封端、低覆盖度硅胶基质C18化学，可为受硅醇基作用影响的化合物提供其它选择性。HSS C18 SB色谱柱硅醇活性提高，使得碱性化合物的保留更强(由于与残留硅醇基的次级作用)，同时降低了对非碱性分析物的保留
(由于其低配体密度以及离子推斥性)。该保留特征的组合产生了一种有用的方法开发工具，可为碱性分析物提供不同的选择性(SB：Selectivity for Bases)，同时还可保持优异峰形。
A rapid and simple LC-MS/MS method was developed and validated for the simultaneous estimation of sofosbuvir (SF) and its metabolite GS-331007 (GS) using famotidine as an internal standard (IS). The Xevo TQD LC-MS/MS was operated under the multiple-reaction monitoring mode using electrospray ionization. Extraction with ethyl acetate was used in sample preparation. The prepared samples were chromatographed on Acquity UPLC HSS C18 (50 mm × 2.1 mm, 1.8 μm) column by pumping 0.1% formic acid and acetonitrile (50:50, v/v) in an isocratic mode at a flow rate of 0.3 ml/min. Method validation was performed as per the FDA guidelines and the standard curves were found to be linear in the range of 10–2500 ng/ml for both SF and its metabolite. The intra-day and inter-day precision and accuracy results were within the acceptable limits. A very short run time of 1.2 min made it possible to analyze more than 300 human plasma samples per day. The developed assay method was successfully applied to a bioequivalence study in human volunteers.
