H-1 CRAMPS and MAS-only NMR experiments have been examined systematica
lly from a quantitative point of view. Silicone rubber was characteriz
ed as a proton NMR intensity standard and found to be successful in qu
antitative analysis for typical solids. Important parameter variations
involved in the CRAMPS experiment, especially for quantitative analys
is, are discussed. The application of the silicone rubber intensity st
andard for quantitative H-1 NMR analysis (spin-counting) to silica is
described, demonstrating the utility and power of H-1 NMR for quantita
tive analysis.
