Chromatography:

Chromatography ID:CH000480
Chromatography Summary:The liquid chromatography platform consisted of an Acquity UPLC system (Waters, Milford, MA). Plasma metabolite separation was achieved using both hydrophilic interaction chromatography (ethylene-bridged hybrid 2.1 × 150 mm, 1.7 μm; Waters) and reversed-phase liquid chromatography C18 (high-strength silica 2.1 × 150 mm, 1.8 μm; Waters). For each column, the run time was 20 min at a flow rate of 400 μL/min. Reverse-phase chromatography was performed using 99% solvent A (5 mmol/L NH4 acetate, 0.1% formic acid, and 1% acetonitrile) to 100% solvent B (95% acetonitrile with 0.1% formic acid). The gradient was 0 min, 0% B; 1 min, 0% B; 3 min, 5% B; 13.0 min, 100% B; 16 min, 100% B; 16.5 min, 0% B; and 20 min, 0% B. Other LC parameters were injection volume 5 μL and column temperature 50°C. Each sample was injected in triplicate with blank injections between each sample. Quality controls and standards were run at the beginning and end of the sequence.
