5 μm particle size) or equivalent columns that guarantee baseline separation for furosine without interfering with other peaks. Gradient elution was performed using solvent A (0.4% acetic acid solution) and solvent B (0.3%potassiumchloride solution) starting at 100% A. Flow rate was set to 1.2...
Additionally, 1H line width reflects the change in the dynamic of the oil molecules concerning oil concentration. The decreasing 1H line width with increasing oil concentration is consistent with the increased mobility within more massive oil clusters. Using continuous flow hyperpolarized 129Xe NMR, ...
2.4. Synthetic Procedures 2.4.1. Synthesis of Triblock PCL-PEG-PCL Copolymer The PCL-PEG-PCL triblock copolymer was synthesized by ring-opening polymeriza- tion (ROP) of ε-CL on PEG and in the presence of stannous octanoate as catalyst under nitrogen atmosphere. In detail, 0.5 g of ...
