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 simultaneously collects high-resolution spectral data over a wide spectral range.

2023年7月8日 · FTIR spectroscopy investigates the interactions between matter and electromagnetic radiation, which appear as a spectrum. FTIR spectrum analysis has enabled the diagnosis of various organ diseases as well as the quantification of various biomolecules such as proteins, nucleic acids, and lipids.

What is FTIR? 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).

2024年5月29日 · A Fourier Transform Infrared Spectrometer (FTIR) is a based on the interferometer. The interferometer in an FTIR works on the same principles as the one used in the Michelson–Morley experiment. The Michelson–Morley showed that the speed of light is the same in all directions; a key finding supporting special relativity.

Explore the power and versatility of Fourier transform infrared spectroscopy (FTIR). Learn about the FTIR principle, how FTIR works, FTIR applications, results, and more.

Infrared, or IR, spectroscopy is a chemical analysis technique that takes advantage of the interaction between infrared light and matter. Infrared light is part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 780 nm to 1 mm.

2024年11月5日 · What is FTIR Spectroscopy? FTIR deals with the infrared region of the electromagnetic spectrum, and it works by measuring how much light is absorbed by the bonds of vibrating molecules to provide a molecular fingerprint. The infrared spectrum can be split into near IR, mid-IR and far IR.

2022年8月4日 · FT-IR stands for Fourier Transform Infrared. It is a fast and dynamic technique for collecting infrared spectra of an enormous variety of compounds for a wide range of industries.

2023年3月16日 · Two important characteristics of an FT-IR spectrophotometer are to have an accurate location of the zero position and a highly reproducible movement of the mirror. …

2023年4月25日 · FTIR spectroscopy offers simple, non-destructive, and reliable sample analysis both qualitatively and quantitatively. The specificity of the IR spectrum produced allows rapid ‘chemical fingerprinting’ of samples with endless applications from industry to academia.
