Polymer characterization by NMR

NMR can be used to identify the type(s) of polymer(s) in a sample by studying the unique response of their nuclei to an applied magnetic field. This technique can be used to characterize a completely unknown polymer or a blend of polymers.

NMR can also be used to study the purity or contamination of a polymer sample. During polymer synthesis, compounding, or manufacturing, materials can become mixed with unwanted polymers or other organic contaminants. NMR can identify these molecules and quantify their concentration in the sample relative to the intended polymer composition.

The processed spectrum is delivered as an image file. Additional interpretation and raw data can be provided upon request.

Please contact Measurlabs' NMR experts to receive a testing plan tailored to your material and analysis needs. 1H-NMR and/or 13C-NMR may be used for this analysis based on the sample. Solid-state measurements are also available.

The price of the measurement can depend on whether your samples require the use of specialized deuterated solvents or measurement conditions (i.e. high temperatures or long measurement times).
