Many spectroscopic methods of analysis are used to answer the question: “What is it?” Great polymer structure analysis requires that additives and fillers be removed. Also, polymer blends need to be separated into individual fractions. Then, end-groups, side-groups, co-monomer contents, and sequence distributions can be deduced.

Approaches
We have performed polymer structural analysis for a variety of purposes. Analysis of polymers and critical comparison with patent claims, to evaluate misappropriation of trade secrets, to assist with identifying additional material suppliers, and for determining root cause of product failures.

Sample Considerations
At the simplest level, a polymer identification can be made using Fourier Transform Infrared (FTIR) Spectroscopy with a sample as small as the period in this sentence.
When a client requires a high level of detail Nuclear Magnetic Resonance (NMR) Spectroscopy is applied in this case, typically carbon and proton NMR. Silicon, fluorine, and phosphorus NMR spectra can also be acquired.
In some cases, polymer structure analysis can be provided using X-Ray Photoelectron Spectroscopy (XPS), a particularly powerful technique for thin coatings and surface layers.
