FTIR Spectro, an FTIR Spectrophotometer Manufacturer, knows how vital molecular analysis is in today’s modern lab. There are several analytical techniques available, and Fourier transform infrared (FTIR) spectroscopy is one of them. The application of this technique is used in determining chemical bonds as well as characterizing materials in relation to their behavior to infrared radiation. The technique is widely used in pharmaceuticals, chemistry, polymer, food testing, and research laboratories in order to determine contaminants and substances.
Principle of Fourier Transform Infrared Spectroscopy
FTIR spectroscopy works on the principle that molecular bonds absorb infrared radiation. Each bond has a characteristic frequency of absorption for infrared energy that is unique to the energy vibrations of that bond. These absorption patterns give rise to a spectrum, which is like the molecular fingerprint.
The positions and intensities of the bands in the spectrum can be used to determine the presence of functional groups in a molecule and for the comparison of the spectra of unknown molecules with a reference spectrum. The results will vary based on the sample preparation, the conditions of the measurement, and the proper interpretation of the spectrum.
How Does an FTIR Spectrophotometer Work?
The FTIR spectrophotometer is an instrument that captures spectral data by means of an infrared source, interferometer, sample compartment and detector.
The process is normally as follows:
Infrared emission: The source emits infrared radiation at a variety of frequencies.
Interferogram: Modulating the radiation with the interferometer to create an interferogram with information on several infrared frequencies.
Sample interaction: The radiation interacts with the sample and is absorbed by certain wavelengths based on the molecular structure of the sample.
Signal detection: The detector will record the resulting signal.
Spectrum generation: The interferogram is transformed into a spectrum by software to be analyzed.
Depending on the sample, measurements can use transmission or attenuated total reflectance (ATR). ATR is especially good for the analysis of many solid and liquid samples without extensive preparation.
Applications of FTIR Spectroscopy
FTIR spectroscopy can be used for a variety of analytical applications:
Pharmaceuticals:
Identification of raw materials and study of chemical composition of pharmaceuticals.
Polymers and plastics:
Characterization of materials; comparison of formulations and investigation of material degradation.
Food testing:
Assisting ingredient identification and chosen food authenticity studies.
Chemical industries:
Recognition of chemicals and detection of changes in chemical processes.
Environmental analysis:
Analyzing appropriate samples and collected materials for specific pollutants.
Research and education:
In this area is helps in the study of molecular structures, functional groups, and material properties.
The method used depends on the sample, the substance to be analysed and the analytical objective of the laboratory.
Advantages of FTIR Spectroscopy
FTIR analysis has several practical benefits. It can obtain the spectral information in a short period of time, needs less sample treatment in many applications, and can give detailed information on the molecular structure. It can analyze various sample types such as solids, liquids and gases, with the aid of an appropriate sampling accessory. Non-destructive or at least minimally destructive, depending on the sampling technique, many measurements are possible.
The above features make FTIR useful for routine identification, material comparison, and research. Appropriate calibration, instrument performance, sample handling, and correct interpretation are still required to obtain reliable results. And we feel responsible to provide the best equipment to labs worldwide as an FTIR spectrophotometer exporter.
