The exact model used in this research was the Perkin Elmer (Model Spectrum Two) for taking spectrum data in the wavelength range of 4000-7000 cm-1. FTIR spectra The analysis of a spectrum obtained from a biomaterial sample allows having knowledge of the molecules and concentration of those that compose the biomaterial. Although the infrared(IR) region has three spectral regions: near IR, mid-IR and far IR ( see Figure 1 ), the region for material characterization most commonly used is the mid-IR due to in this area are the principal Some spectra will use absorbance values or reflectance values instead of % transmittance. The variables used will be chosen based on the desired goal of the study. This older style was replaced by the FTIR or Fourier Transform Infrared Spectrometer.

FTIR Spectroscopy allows investigating the response function of a material, i.e. optical conductivity, as a function of frequency. For this reflectance or transmittance

The exact model used in this research was the Perkin Elmer (Model Spectrum Two) for taking spectrum data in the wavelength range of 4000-7000 cm-1. In FTIR, the clarity of the spectra (i.e., the sharpness of the peaks) obtained can be changed by selecting a different aperture.

The most common use is in the identification of unknown materials and confirmation of production materials (incoming or outgoing). The information content is very specific in most cases, permitting fine discrimination between like materials. FTIR graph are collectively known as the fingerprint region.
