Structural identification by NMR of catalysts, active pharmaceutical products and polymers

Solid State Nuclear Magnetic Resonance (NMR) is a specialized characterization technique used to determine chemical composition or structural properties in a variety of industrially relevant materials. Solid State NMR brings the benefits of solutions NMR (detailed chemical structural information and quantitation) without the need for standards. Intertek scientists leverage the unique application of this technique in combination with others such as Raman or powder x-ray diffraction to solve challenging material or process problems. Applications include:

  • Heterogeneous catalysts used for chemical manufacture, petroleum processes, purification, and air separation
    • Determine framework composition of zeolites and changes with activation or use
    • Identify sorbed species in porous materials
    • Characterize key functionalities in insoluble residues
  • Crystalline structure of pharmaceutical products
    • Determine polymorphs generated by different recrystallization processes and conditions
    • Characterize crystalline form of a drug present in a final product
    • Complementary tool to Raman and X-Ray Diffraction (XRD) for polymorph characterization
  • Determine chemical composition in range of insoluble polymers and plastics
    • Identify and quantify components in polymer blends without need for calibration standards
    • Polyethylene, polypropylene, nylons and other industrially relevant blends

Consult with a skilled team of Intertek material scientists to determine how solid state NMR or other analytical techniques can answer your particular structural or process question.
