Fourier transform infrared spectroscopy (FT-IR) is a well-established technique that has been widely used in the field of materials analysis. CD BioGlyco has advanced FT-IR testing equipment and a professional FT-IR testing technical team to provide clients with professional qualitative and quantitative analysis of polysaccharide-based biodegradable materials.

FT-IR Analysis

Infrared spectroscopy belongs to molecular spectroscopy and has the advantages of high sensitivity, accurate wave number, and good repeatability, making it a promising tool for determining the composition and structure of molecules. FT-IR is a powerful infrared spectroscopy technique, which is based on the Fourier transform of interfering infrared light to generate a molecular fingerprint representing the structural characteristics of a sample. The technique allows the determination and differentiation of different molecular structures and has been widely used to analyze and identify substances and study interactions within and between molecules, etc.

FT-IR provides well-divided absorption regions of characteristic groups, which enables a simplification of the interpretation process and provides useful information for the identification of polysaccharides. Based on the observation of characteristic absorptions, this technique has been widely used for the structural characterization of Carbohydrate-based Biodegradable Materials. The low cost, high efficiency, non-destructive, high accessibility, and high sensitivity make FT-IR a widely accepted technique for routine analysis and quality control of polysaccharide-based biodegradable materials.

FT-IR Analysis of Polysaccharide-based Biodegradable Materials at CD BioGlyco

We offer our clients FT-IR analysis, which is a mature technology for evaluating quality control when manufacturing polysaccharide-based biodegradable materials. Our FT-IR analysis is suitable for films, solids, powders, particles, liquids, or gases, as well as pure substances or mixtures, allowing quantitative or qualitative analysis. Our FT-IR analysis services include, but are not limited to:

• Qualitative characterization of polysaccharide-based materials
  • Identification of polysaccharide types and the existence of specific polysaccharides in complex systems.
  • Identification of substitution groups in polysaccharide-based materials, including phosphoryl, acetyl, sulfonyl, and carboxymethyl groups.
  • Identification of anomeric carbon configurations.
  • Identification of crystal allomorphs.
• Quantitative characterization of polysaccharide-based materials
  • Determination of polysaccharide content.
  • Determination of substitution degrees, such as the degree of methylesterification (DM), degree of O-acetylation substitution, degree of N-acetylation (DA) substitution, and degree of carboxymethyl starch (CMS) substitution.
  • Determination of crystallinity index.
• Identification and characterization of unknown materials
• Identification of contamination on or in polysaccharide-based materials
• Characterization of changes in the chemical structure of polysaccharide-based materials
