Add 700 ul of the filtered solution to a clean 5 mm NMR tube, and cap and label the tube. For the liquid samples, use about 700 ul spiked with 1-2 % TMS. As a general guide, a sample concentration of ...

Common NMR active nuclei are 1H, 13C, 31P, 15N, 29Si, and many more. Nearly every element has at least one isotope that is NMR active. Since then, NMR spectroscopy has become an indespensible tool for ...
