Solid State NMR is a technique capable of providing information about structure and dynamics of molecules. It provides a structural characterization of polymers, inorganics, inorganic-organic composite materials, etc.. Although the principle is common to the NMR in solution, the equipment requires specific accessories that allow it to obtain high-resolved spectra. The most important difference from liquid-NMR is the capability of investigating conformations, crystalline phases, molecular packing and intermolecular interactions. 

Time Domain NMR (Low Res). It is an alternative to classical NMR and is performed on a benchtop low-field instrument operating in time-domain only. From relaxation curves information regarding 1H/19F content, rigid/soft phase content, water content can be obtained. Advanced investigations can also be performed, e.g. analysis of crosslinking, degree of polymerization and  domain sizes in polymer-based materials.

SS-NMR. Analyses can be performed on powders, soft rubbers and films. Depending on the sample constituents, suitable experiments are performed. 

For example, the chemical structure of a common polymer is obtained  with a multinuclear approach (1H/19F/13C), but more complex experiments or variable temperature measurements can also be run for assessing further structural information.

• T range:  -40° <-> 100°C
• Most common investigated nuclei: 1H, 19F, 13C, 29Si, 31P, 27Al, 7Li

TD-NMR. Analyses can be performed on liquid, solid or heterogeneous samples. The only limitation is that the sample can be inserted in a 10 mm glass tube. Quantitative investigations require a prior calibration with reference samples. Depending on customer needs, suitable experiments can be developed.

• T range:  -80° <-> 100°C
• Nuclei: 1H, 19F
