Ramped amplitude cross polarisation magic angle spinning NMR (Ramp-CP-MAS-NMR): A technique for quantitative study of the composition of solid state polymers
A method based on ramp amplitude cross polarization is presented for the quantitative NMR analysis of solid amorphous complex heterogeneous polymeric samples. A non-mathematical theoretical explanation of the method and how it applies to such samples is given. Experimental results showing the superior performance of the ramp amplitude cross polarization method over the typical single amplitude cross polarization mehtod are presented. A brief introduction to biogeopolymers, i.e. fulvic and humic acid, and the possibility of NMR in their analysis is also presented. © 1999 OPA (Overseas Publishers Association) Amsterdam B.V.
