http://cerexmonitoringsolutions.com/products WebNicolet iS™5 FT-IR spectrometer is capable of measuring this effect (as are the Nicolet iS10 or Nicolet iS50 FT-IR systems). The absorptivity of ammonia is quite high, so a 5 cm pathlength gas cell provides plenty of absorption. The gas cell should be loaded with ammonia vapor at low pressure, typically about 5–10 psi (or up to 1 atm, which
WebMar 28, 2024 · Meanwhile, FTIR was performed to characterize PDA NPs (Fig. 2 C). The wavelength bands observed at 3350–3450 cm −1 corresponded to the ν (O–H) and ν ( N –H) functions, which represented the phenolic hydroxyl and amino groups of P. WebPresented in Figure 6, these two spectra clearly demonstrate that FTIR made it possible to monitor the gas precursor consumption upon plasma deposition, as the ab- sorbance of the 965 cm −1 ...
