PA6与PA66材料中较明显的特征峰有3 300 cm-1附近的胺基吸收峰、2 932 cm-1附近与2 860 cm-1附近的亚甲基吸收峰、1 633 cm-1处的酰胺Ⅰ峰(C=O伸缩振动引起)、1 536 cm-1附近的酰胺Ⅱ峰(N—H变形振动引起)、1 460 cm-...
FTIR spectra reveal the composition of solids, liquids, and gases. The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information...
Fig.3 FTIR spectra of thiophene or hexane adsorbed on sulfided catalysts, as well as CO adsorbed under different sulfided conditions[49,57] (a) Sulfided CoMo/Al2O3adsorbed CO before (1) and after adsorbed thiophene (2) and hexane (3); (b) Sulfided MG-M MG-E and SR-M SR-E 5.2...
FCM will collect spectra. FCM will calculate concentrations of multiple gas components using classical least squares (CLS) in the gas cell. FCM will do “real time” concentration and display of concentrations of gas in a gas stream or kinetics experiment. ...
ly (0112) faces and, to a less extent, (2116) and (1120) faces, we have compared the IR spectra of CO adsorbed on high surface area and sintered α-Cr 2 O 3 samples, with the aim to evidentiate the effect of increasing defects concentration on the IR spectra of the adsorbed CO....
