Enabling Quantitative Benchtop <sup>13</sup>C NMR Spectroscopy in Fast Continuous Flow. [PDF]
Magn Reson ChemParamagnetic relaxation enhancement (PRE) accelerates polarization buildup in continuous‐flow benchtop 13C NMR spectroscopy by the use of an immobilized PRE agent. By combining PRE with PENDANT polarization transfer, weak 13C signals are enhanced even at high flow rates, enabling robust quantitative analysis of solvent mixtures under process‐relevant ...
