FTIR Spectroscopy Analysis

FTIR is an acronym derived from Fourier transform infrared spectroscopy, which stands for Fourier transform infrared spectroscopy.

This analysis method, known as FTIR analysis or FTIR spectroscopy, is an analytical test method used to identify organic, polymeric and in some cases inorganic materials. The product composition analysis method with FTIR uses infrared light to scan test samples and observe chemical properties.

The device used in the analysis sends infrared radiation from a sample by absorbing some radiation and passing some radiation. The absorbed radiation is converted into rotational or vibrational energy by the sample molecules. The resulting signal in the detector represents the molecular fingerprint of the sample, and each molecule or chemical structure produces a unique spectral fingerprint, making it a great tool for chemical identification.

FTIR analysis, or FTIR spectroscopy, is an established technique for quality control when evaluating materials produced in various industries and often serves as the first step in the material analysis process. If problems with the material are detected by visual inspection, the source is typically determined by FTIR micro-analysis. This technique is useful for analyzing larger areas on the surface as well as the chemical composition of smaller particles, generally between 10 and 50 microns.

Product composition analysis with FTIR is mainly used for the following purposes:

• Identifying and characterizing unknown materials such as films, solids, powders or liquids
• Identifying contamination on or in a material, such as particles, fibers, powders or liquids
• Identifying additives after extraction from a polymer matrix
• To identify oxidation, segregation or uncured monomers in failure analysis investigations

In the industry, FTIR spectroscopy is a very powerful tool in many applications, but data interpretation is not easy. By its very nature, the total spectrum produced is a set of functions of the absorbed energy response.

For example, in the cosmetics industry, the rapid identification of cosmetics is especially important in warehouses that witness large amounts of product arrivals every day. FTIR spectroscopy offers the advantage of measuring a small amount of sample (a few milligrams or milliliters) in the least amount of time.

Cosmetic products are widely used by a large part of the population. Contrary to popular belief, cosmetic products are not completely safe to use and cause serious side effects. The long-term damage caused by the irregular use of these products is still unknown. In this respect, there is a need to develop analytical techniques used to scan accurate, fast and large numbers of series. One of these methods is FTIR (Fourier transform infrared spectroscopy) technique.

This technique is a classic technique widely used in the pharmaceutical industry, because it is fast and non-destructive and requires minimal sample preparation. Recently, this technique has been used in the cosmetics industry for product characterization, stability, identification of contaminants and forensic identification of crime scene samples.

Briefly, FTIR (Fourier transformed infrared spectroscopy) is a method applied to analyze both organic and inorganic materials. With this method, the chemical structure of a material is analyzed by examining the chemical bonds and composition. FTIR technique is useful for both organic and inorganic materials. In addition, with this method, covalent bond pairs and functional groups in a material are determined.

The FTIR method takes advantage of the light absorption of a material, using the way different molecular compounds react to infrared light to determine the structure of the material being analyzed. This method is also known as absorption spectroscopy and is applied in a variety of ways, including polishing a beam of light with a limited frequency group or using monochrome light. This technique exploits the fact that each frequency reacts differently to the material and works by using more than one different frequency in the beam. In this way, the composition of an unknown material is accurately determined.

On the other hand, material deterioration is also detected with the FTIR technique. Materials are tested under real time or accelerated conditions. This technique is used to test impurities in a material or compound, as well as raw materials, drugs, and medical device materials.
