Fourier-transform infrared spectroscopy energy throughput

Fourier transform infrared spectroscopy provides higher-resolution capabilities without undue sacrifices in energy throughput or signal-to-noise ratios. 

Infrared spectroscopy has been one of the most frequently used instrumental analysis methods to characterize the surface functionalities in coals [231, 232], carbon blacks 233], charcoals [234], activated carbons [61, 208, 235-238] activated carbon fibers [239, 240] and carbon films [241, 242], Since its introduction, Fourier transform inlrarcd (FTIR) spectroscopy has foimd a wide application to both qualitative and quantitative analysis of the carbon materials. One of the reasons for its application was the fact that meaningfi.il information is often difficult to obtain by conventional transmission / absorption. The Fourier analysis provides an improvement of the signal-to-noise (S/N) ratio, higher energy throughput, greater accuracy of the frequency scale, and the capacity for versatile data manipulation, in competition with dispersive IR-spectroscopy.
