Ftir: Learn how a Fourier Transform Infrared

Learn how a Fourier Transform Infrared Spectrometer (FTIR) works based on the interferometer and the Fourier transform. See how the interferogram and the spectrum are related and how they can be used to identify molecules. 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 ... Fourier transform infrared spectroscopy (FTIR) [1] is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer collects high-resolution spectral data over a wide spectral range. 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.
