Basic Principles of Fourier Transform Infrared Spectroscopy (FTIR)

2025-11-24

Fourier transform infrared spectroscopy (FTIR) can be categorized based on the spectroscopic technique used: Fourier transform infrared spectrometers (FTIR) and dispersive infrared spectrophotometers (Dispersive). The main difference lies in the specifications of the interferometer and computer. Most interferometers currently used are Michelson interferometers, which transmit the signal from a light source in the form of an interference pattern to a computer for Fourier transform mathematical processing, ultimately reconstructing the interference pattern into a spectrum. A Michelson interferometer primarily consists of a light source, a fixed mirror, a moving mirror, a beam splitter, and a detector.

Beijing Airppb Environmental Protection Equipment Co., Ltd. has launched the MR-ACT intelligent research-grade Fourier transform infrared spectrometer (FTIR) series. This instrument can not only identify gas types from up to 5 kilometers away, but also detect over 500 toxic and hazardous gases, and visualize the gas dispersion on a computer screen. Based on extensive user feedback, this product boasts excellent portability, can be carried in vehicles or boats, and boasts excellent three-proof performance. It can be seen at major exhibitions, allowing for on-site release testing of non-toxic and harmless gases within venues. Its rapid and accurate response makes it a proven, mature and stable product,Customers rushed to buy it. latest company case about [#aname#]
