The techniques of Fourier transform infrared microspectroscopy are reviewed. The technique which can be used to obtain the infrared transmission and reflection infrared spectra of very small samples is extremely useful for the characterization of a variety of chemical systems such as polymers, biological materials, and semiconductor materials. In this paper, the applications of the microspectroscopic techniques to the characterization of polymer systems will be illustrated and discussed. The method can be used to identify contaminants in polymer materials, identify different layers in multi-layer polymer packaging materials and characterize paint samples. Unlike other microsampling methodologies, the infrared microsampling techniques will yield direct information about organic materials and functional groups and has the potential to solve a number of real life, industrial problems.
