Description

Molecular absorption spectrometry in infrared is an analytical technique useful in the first thing for qualitative analysis such as inorganically substances and, especially, for organically substances, based on characteristic of absorption spectra, due to atoms vibrations in frame of different groups from analytical molecules. Chemical information can be obtained from almost any material, such as films, powders, solutions, plastics, tablets, paper, fibers, cells, biological tissues, and many more.
