Then find the corresponding values for … WebFTIR is an excellent technique to study Selective Catalytic Reduction (SCR) compounds, including NO, NO₂, N₂O, and NH₃. These methods are configured with the Thermo Scientific 2-meter gas cell and a liquid-nitrogen cooled MCT-A detector. Detection limits are based on a 3-second sample time.
Fourier-transform infrared spectroscopy (FTIR) 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. This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths a… WebFTIR is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms FTIR - What does FTIR stand for?
