Fourier Transform Infrared Spectroscopy (FTIR) is an infrared spectroscopy technique, which unlike other infrared spectroscopy techniques, is not dispersive. This enables FTIR to have good ...

Fourier transform infrared (FTIR) spectroscopy is the preferred method of infrared spectroscopy. In this approach, IR radiation passes through a sample, where some of it is absorbed by the sample ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

Non-Dispersive Infrared (NDIR) spectroscopy is by far the most commonly used gas detection method. Infra-red radiation generated by a broad band emitter is passed through the gas which is contained in ...
