To help make your job easier, we outlined the basic organic functional groups, their positions of infrared bans, their relative peak intensities, and their functional group representation. Download this easy-to-readchart. Looking for more basic FTIR information, be sure to visit ourFTIR Spectros...
Infrared spectrum chart peak positions were basically the sameꎬ and the chemical composition were roughly the same. They were composed of carbohydrateꎬ proteinꎬ lipid and other biological molecular vibration spectrum band. From 1 800 to 1 000 cm~1 for second derivative conductionꎬ the ...

The data volume was intentionally limited so as not to overload the chart while at the same time giving the widest possible range of panel thickness. It can be clearly seen that the isocyanurate/phenyl ratio of all PIR foams dramatically increases from the surface toward the core of the foam...
