Fourier Transform Infrared (FTlR) Spectroscopy

Fourier Transform Infrared (FTlR) Spectroscopy


Fourier transform infrared (FTlR) spectroscopy is an experimental technique used to probe the molecular structure and chemical bonding of materials. As a powerful tool, FTlR spectroscopy can help researchers gain insight into the molecular structure of a wide range of compounds, inorganic or organic, macromolecular or oligomolecular, and thus provide important information for materials research and development. The technology plays an important role in the fields of medicine, food, and materials science.

Working Principle

When the sample under test is irradiated with infrared light at a changing frequency, the molecular groups absorb radiation at a specific frequency. This causes a change in the dipole moment due to vibrational or rotational motion within the molecule, which triggers a jump between the vibrational and rotational energy levels of the molecule from the ground state to the excited state, forming the absorption spectrum of the molecule.


  • Strong characterization, each substance has its unique spectrum.
  • Fast analysis, only a few seconds to minutes to complete a measurement.
  • Does not destroy or alter the properties of the sample.
  • Only a very small amount of sample is required for analysis.
  • High analytical sensitivity, capable of detecting trace amounts of substances.
  • Wide range of applications, including inorganic, organic, and polymer compounds.

CD BioSciences, a pioneering biotechnology company, endeavors to provide Fourier transform infrared (FTIR) spectroscopy services to the materials, biomedical, food industry, and chemical sectors.

Main Applications

  • Biomedical

FTlR spectroscopy can assist in analyzing the structure and composition of new drugs and plays a key role in modern pharmacology in the development of new drugs. We provide FTlR spectroscopy not only for drug analysis, efficacy evaluation, and disease diagnosis but also for the study of the structure and function of biological macromolecules such as proteins, DNA, and drugs.

  • Environmental Monitoring

We utilize FTlR spectroscopy technology to detect organic pollutants, heavy metals, and other toxic substances in environmental samples, providing a scientific basis for environmental protection and pollution control. In addition, it can also be used in the calibration and detection of environmental monitoring instruments, etc.

  • Material Science

We can offer FTlR spectroscopy to characterize the molecular structure and chemical composition, structure and properties of polymers, coated materials, nanomaterials, and other materials.

  • Food Industry

Due to food safety concerns, FTlR spectroscopy is widely used to detect ingredients, additives, and contaminants in food. We provide FTlR spectroscopy for food safety testing, quality control, and production process optimization to ensure food quality and safety. In addition, we can use the technology to detect and control food processing online.
