QUANTITATIVE-ANALYSIS OF SOLIDS BY HIGH-RESOLUTION H-1-NMR

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.
