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.

FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted).

We briefly explain the fundamentals of infrared (IR) spectroscopy and focus on the basic questions about FT-IR, ATR, transmission and reflection.

2023年7月8日 · FTIR is a unique approach for characterizing the variation in fuel stability of several biodiesel /antioxidant mixtures. In most failure analysis investigations, it is used to determine breakdown, oxidation, and uncured monomers.

2018年7月16日 · FTIR analysis is used to identify molecular compounds. It works by measuring the absorbance of infrared radiation by a sample. The resulting spectrum can then be used to identify the functional groups present in the compound.

Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties.

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).

FTIR spectrometers’ advanced scanning capabilities is step-scan. In step-scan, the moving mirror moves incrementally in steps. Step-scan eliminates Fourier modulation interference encountered in continuous-scan FTIR and allows measurements to be made as …
