Nuclear Magnetic Resonance Spectroscopy (NMR) :: Polymer Solutions Incorporated - Providing Quality Answers Through Independent Chemical Analysis, Physical Testing, and Research & Development.

Nuclear Magnetic Resonance Spectroscopy (NMR)

NMR is a quantitative technique for analyzing soluble materials or extracts to determine the organic chemical components of a sample. The most commonly used elements analyzed for structural determination of organic polymers and small molecules are proton (¹H) and carbon (¹³C). Other elements can be analyzed as well, such as silicon (²⁹Si) and fluorine (¹⁹F).

NMR is a complimentary technique to FTIR. The PSI scientists can help you to determine which method is right for your analytical objectives.

Applications:

Chemical identification
Polymer Identification
Copolymer and blend ratio determination
Identification and quantification of contamination
End group analysis
Material certification
Competitor product analysis

Work We've Done

Nylon Analysis

A client needed to know the copolymer levels of nylon in a material they were producing under different process conditions. We were able to determine the nylon copolymer ratios present in the sample using ¹³C NMR.

Polyethylene Analysis

A client was experiencing sudden failures in a molded HDPE product. ¹³C NMR comparing a “good“ lot of the product and the “bad” lot of the product indicated significant differences in the grade of polyethylene used in the manufacture of the product. The client was able to trace the failure back to their polymer compound supplier.
