What are the applications of FTIR spectroscopy?

FTIR spectroscopy is used to quickly and definitively identify compounds such as compounded plastics, blends, fillers, paints, rubbers, coatings, resins, and adhesives. It can be applied across all phases of the product lifecycle including design, manufacture, and failure analysis.

What are the most common applications of FTIR?

FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials.

What are the uses of FTIR in the forensic laboratory?

FTIR analysis is used to spot unknown materials and/or quantify surface contamination on a material. Due to the speed and simplicity of the process, FTIR analysis is a preferred material analysis technique.

What is the principle of FTIR spectroscopy?

FTIR spectrometers rely on the same basic principle as NDIR analyzers, i.e., the fact that many gases absorb IR radiation at species-specific frequencies. However, FTIR spectroscopy is a disperse method, which means that measurements are performed over a broad spectrum instead of a narrow band of frequencies.

How FTIR is practically useful in your research?

Fourier transform infrared (FTIR) spectroscopy is particularly useful for online monitoring of polymer composition. Its ability to fingerprint chemical components allows FTIR to determine the constituents of a chemical process. It has been applied to the analysis of solid, liquid, and gaseous process streams.

Why is FTIR is useful in organic synthesis?

FTIR is widely used in many industries and is used for the analysis of both organic and inorganic compounds. It can confirm the composition of both solids, liquids, and gases. FTIR is mainly used for: The identification of unknown compounds.

How is spectroscopy used in forensics?

Forensic scientists can use spectroscopy methods to reveal the chemical make-up of blood samples and other bodily fluids. Electromagnetic radiation (usually from precisely calibrated lasers) is applied to the fluid sample.

Why is Microspectrophotometry useful to a forensic technician?

In forensic science, MSP is most commonly used to measure and compare the color of single fibers. This can be done using unpolarized light or plain polarized light (to study pleochroism). Paints, minerals, and a variety of other trace evidence can also be studied.

What are the components of FTIR?

The three major parts of an FTIR are the source, interferometer, and detector (Figure 4).

What type of information can be obtained from FTIR?

FTIR is a rapid, nondestructive, time saving method that can detect a range of functional groups and is sensitive to changes in molecular structure. FTIR provide information on the basis of chemical composition and physical state of the whole sample (Cocchi et al. 2004).
