%. UPLC-MS/MS instruments and parameters An API 5500 Triple Quad UPLC-MS/MS System (AB SCIEX, USA) was employed for UPLC-MS/MS analysis. Waters ACQUICY BEH C18 (2.1 × 100 mm, 1.7 μm) was selected as analytical column in this
pressure, which provides the ultra-performance liquid chromatography (UPLC) separation on a conventional HPLC system [ 17 , 18 , 26 ]. Hence, combining the advantages of HPLC-MS and poroshell column would be a good strategy to develop a rapid analytical
The experiment was manipulated on an UPLC Acquity C 18 column (2.1 mm × 100 mm, 1.7 µm) maintaining at 40 °C. The mobile phases were consisted of solvent A (5 mmol/L ammonium acetate and 0.1% formic acid solution) and solvent B (acetonitrile) with a
