FTIRIS stands for Fourier Transform InfraRed Imaging Spectroscopy. It is an analytical technique that combines the principles of spectroscopy, imaging, and Fourier transform infrared (FTIR) spectroscopy.
FTIRIS involves the use of infrared radiation to analyze the chemical composition of a sample. Infrared radiation has energies corresponding to the vibrational frequencies of molecules, and by measuring the absorption, transmission, or reflection of this radiation, information about the chemical bonds present in the sample can be obtained.
The Fourier transform technique in FTIRIS is used to convert the resulting interferogram into a spectrum, which contains detailed information about the sample's composition. This enables the identification of chemical functional groups and the analysis of molecular structures.
FTIRIS is also an imaging technique, allowing the spatial distribution of chemical components to be visualized. By combining spectroscopy and imaging, it enables the investigation of heterogeneity within a sample, such as the identification and localization of different compounds within a complex mixture.
This analytical tool finds applications in various scientific fields, including materials science, pharmaceutical research, forensic analysis, environmental monitoring, and bioimaging. It can be used to identify and characterize unknown substances, study chemical reactions, investigate the properties of materials, detect defects or contaminants, and provide valuable insights into biological systems.
Overall, FTIR imaging spectroscopy is a powerful analytical technique that enables the comprehensive analysis and imaging of samples based on their chemical composition using infrared radiation.
