疏水反相保留機理、硅膠顆粒
與CORTECS，CSH和BEH顆粒相比，ACQUITY UPLC HSS色譜柱為極性與非極性分析物提供更理想、更平衡的保留效果。經過工藝優化的硅膠顆粒，其機械強度與穩定性更能耐受。UPLC系統操作壓力。5種差異較大的鍵合相，提供更寬泛的選擇空間，除了傳統的疏水反相保留機理之外，還有偶極-偶極、芳香與氫鍵相互作用。
ACQUITY UPLC HSS C18 SB色譜柱是一種未封端、低覆蓋度硅膠基質C18化學，可為受硅醇基作用影響的化合物提供其它選擇性。HSS C18 SB色譜柱硅醇活性提高，使得堿性化合物的保留更強(由于與殘留硅醇基的次級作用)，同時降低了對非堿性分析物的保留
(由于其低配體密度以及離子推斥性)。該保留特征的組合產生了一種有用的方法開發工具，可為堿性分析物提供不同的選擇性(SB：Selectivity for Bases)，同時還可保持優異峰形。
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.
