What is Structure Determination (FTIR)? Purpose of Analysis and Method Details

Why is Structure Determination (FTIR) Performed?

What is FTIR?

FTIR (Fourier Transform Infrared Spectroscopy) is a spectroscopy method used to determine the chemical structure of a material or substance. This method provides information about the structure of a substance or material by analyzing its chemical bonds and functional groups. FTIR is widely used in many fields such as chemistry, materials science, biotechnology and food safety.

FTIR Method and Application Areas

Method and Principle:

FTIR spectrometry uses the Fourier transform of a material to provide internal structural information of that material.
Sample Preparation: The sample is usually in powder, liquid or film form. The sample is prepared beforehand and made suitable for analysis.
Infrared Irradiation: The FTIR instrument sends infrared radiation at a specific wavelength to the sample. This beam interacts with the sample and is absorbed.
Conversion and Spectrometry: The absorbed light is analyzed with the Fourier transform algorithm. This transform reveals absorption information against the wavelengths of light.
Spectrograph: The spectrum obtained in the FTIR spectrometer is like a fingerprint of the chemical structure of the sample. It shows characteristic absorption peaks of chemical bonds and functional groups at specific wavelengths.

Application Areas:

Chemical Structure Determination: FTIR is used to analyze the chemical structure of organic compounds. For example, structure determination can be performed on plastics, organic solvents, drugs and other chemical compounds.
Materials Science: It is used in the characterization of new materials, polymers and ceramics. By determining the chemical components of materials, FTIR enables an understanding of the factors that affect the performance of materials.
Food Safety: It is used to analyze the chemical structure of compounds found in foods. FTIR can identify additives and chemical compounds in foodstuffs.
Environmental Analysis: It is used to detect organic pollutants in water, soil and air samples. FTIR is used to determine the structure of chemical compounds in these samples.
Pharmaceutical Industry: Used to check the chemical structure and purity of pharmaceuticals. FTIR plays a critical role in the characterization of drug formulations.

FTIR Spectroscopy is used to rapidly and precisely identify the compounds of products such as compound plastics, fillers, paints, rubbers, coatings, resins and adhesives. The method of using FTIR is the mathematical Fourier transform method and the measurement of the wave number against the infrared intensity of light.

FTIR is used for the determination of material type and additives in plastic packaging materials widely used in the packaging industry. Qualitative and quantitative measurements are made using FTIR in quality control studies in plastic packaging and materials.
