What is the difference between IR and FTIR?
What is the difference between IR and FTIR? FTIR spectrometers have several prominent advantages: (1) The signal-to-noise ratio of spectrum is significantly higher than the previous generation infrared spectrometers. (2) The accuracy of wavenumber is high. Due to these advantages, FTIR Spectrometers have replaced dispersive IR spectrometers. What is the principle of IR spectroscopy? IR […]
