Micro FT-IR Spectroscopy

Fourier Transform Infrared Spectroscopy (Micro FT-IR Spectroscopy) is a powerful analytical tool based on interferometery that compares the returned or transmitted light energy of the IR spectrum to the emitted source spectrum. The result is a spectrum of the infrared energy absorbed by the sample. Covalent bonding vibrational frequencies, such as asymeteric stretching and deformation stretching is determined by correlation to the wavelengths in the IR Spectrum.

Information Obtained
Interpretation of the spectral information provides identification of functional groups or covalent bonding information. Determination of particulate or stained regions of printed circuit boards for failure analysis is possible. Identification of organic coatings on metals, paper and other materials for construction analysis purposes is also a common application. Additionally, a comparison of variations in materials for process control can be provided.
