New CPMAS 13C NMR method for the study of biogeopolymers
A new cross polarization magic angle spinning (CPMAS) 13C NMR technique has been developed which uses high fields, high sample spinning, and the ramp CP pulse sequence. The spinning of the sample at higher speeds overcomes the line broadening due to motional modulation of the resonance frequency via the chemical shift anisotropy (CSA). The method also offers better quantitative reliability, better resolution, and better signal to noise ratio. The method is useful for the study of biogeopolymers, coals, complex polymer mixtures, biopolymers, and other heterogeneous samples.
