Ftir: Learn how FTIR analysis uses infrared light

Learn how FTIR analysis uses infrared light to identify organic, polymeric, and inorganic materials. Find out how FTIR works, what it is used for, and how to interpret the spectra. FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample, and some of it is passed through (transmitted). Fig: Instrumentation of Fourier transform infrared spectroscopy (FTIR) The sample The beam enters the sample compartment where it is transmitted through or reflected on the surface of the sample depending on the type of analytes being accomplished. This is where specific frequencies of energy which are uniquely characteristics of the sample are absorbed. Detector The beam is finally measure after passing through the detector. The detectors used are specifically designed to measure the ... Learn about Fourier Transform Infrared Spectroscopy (FTIR), a technique that measures all infrared frequencies simultaneously and provides a molecular fingerprint of any material. Find out how FTIR works, what are its advantages and limitations, and what are its applications in various fields.
