    Fourier Transform Infrared Spectroscopy (FTIR)

    Fourier Transform infrared spectroscopy, also know as FTIR, is widely used in the qualitative and quantitative analysis of many polymer and inorganic non-metallic materials, such as plastics, rubber elastomers, fibers, coatings, fillers and so on.

    Infrared absorption spectroscopy is mainly used for group structure analysis, qualitative and quantitative analysis of materials.

    • Characteristic absorption frequency - groups (qualitative analysis).
    • Intensity of characteristic peak- quantitative analysis.

    Functions of FTIR

    • Identification of known objects.
    • Structural identification of unknown substances.
    • Quantitative analysis of special materials.
    • Micro-infrared can analyze trace substances such as residues on the surface of the product, powder/liquid precipitated on the surface, and suspected oxidation, corrosion, foreign matter, and introduction of foreign components on the product surface.

    Application of FTIR in the field of material testing

    • Identification of known objects
    • Compare the infrared spectrum of the sample with the standard infrared spectrum. Determine the similarity and purity of the two compounds based on the consistency of the spectral peak position, wave number, peak shape and other characteristics.

    • Consistency determination of polymer materials
      • Application fields: Unprocessed plastic raw materials (granules) or processed and formed homogeneous plastic parts, such as housings, supporting live parts, etc.; printed circuit boards, such as PCB boards.
      • Purpose of material consistency determination: Solve product abnormalities from the aspect of material; monitor the product to determine whether the material is the same composition, the same batch, and the same manufacturer; can effectively control the plastic material supplier's use of excessive recycled materials or scrap; reverse analysis of products, accurate qualitative unknown materials, saving costs.
    • Foreign body analysis
      • Application field: For abnormal substances such as surface contaminants and precipitates on the product, such as particles, oil, mist, spots, etc. on the product surface, FTIR mainly analyzes organic foreign substances.
      • The purpose of foreign matter analysis: To analyze the composition of foreign matter, impurities or unknowns during industrial production, storage, and use, so as to find and track the cause and source of foreign matter, thereby effectively preventing foreign matter from being generated and reducing enterprise economic losses.
    • Curing rate testing
    • The curing rate is a characterization of the degree of curing of the colloidal sample before and after physical curing or chemical curing. Using FTIR to test the curing rate includes: observe the breakage and recombination of the functional groups of the sample during the curing process; the mechanism of the curing reaction; judge the degree of the curing reaction; test the curing rate of the sample, etc.

      • Application field: It is suitable for thermosetting resins such as epoxy resin, polyurethane resin, vinyl addition polymerization silicone rubber, etc.
      • Curing rate test purpose: Curing rate (cross-linking degree) test can effectively observe the degree of reaction of cross-linked cured samples and control material properties.
