Improved NMR-based diffusion measurements for inorganic ions
Abstract
Mg diffusion NMR experiments on DNA solutions, we demonstrate that the bipolar-pair (BPP) spin-echo method provides more than a 2-fold improvement in sensitivity compared to the BPP stimulated-echo method. While both methods yield consistent diffusion coefficients and achieve equally effective suppression of eddy currents, the BPP spin-echo method provides notably improved precision due to its higher signal-to-noise ratio in the NMR spectra. When strong gradients are available, the BPP spin-echo method is a more robust and sensitive option for diffusion NMR of inorganic ions, reducing the measurement time by a factor of 4 compared to the stimulated-echo method.
