| Chromatography Summary: | Samples were analyzed using a Thermofisher Vanquish UHPLC system coupled to a Thermofisher TSQ Altis triple-quadrupole mass spectrometer. An Aquity BEH C18 column (1.7 µm, 2.1 mm×100 mm) with guard column Acquity BEH C18 (1.7 µm, 2.1 mm×5 mm) was used for chromatographic separation with mobile phases of A: LC-MS-grade water with 0.1% formic acid, and B: LC-MS-grade acetonitrile with 0.1% formic acid with a flow rate of 400 µL/min and column temperature of 50 °C. The gradient began at 20% B for 1 min, then shifted to 45% B between 1 and 11 min, then to 95% B between 11 and 14 min, then to 99% B between 14 and 14.5 min, 99% B was maintained until 15.5 min, then transitioned from 99% B to 20% B between 15.5 and 16.5 min, and maintained at 20% B until 18 min. Injection volume was 5 µL and MRM scans were collected for all bile acids and internal standards. |
