WebFT-IR Advantages The modern FTIR spectrometer has three major advan tages over a typical dispersive infrared spectrometer. These advantages are the reason FTIR is now the standard tool, having largely displaced dispersive instru ments by the mid1980’s. Multiplex Advantage As seen from the operations description above, the WebInfrared light is part of the electromagnetic spectrum between visible light and microwaves, with wavelengths ranging from 780 nm to 1 mm. Due to historical reasons however, we …
