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.

Unlike a dispersive instrument, i.e. a grating monochromator or spectrograph, FTIR spectrometers collect all wavelengths simultaneously. This feature is called the Multiplex or Felgett Advantage. Fourier Transform Infrared Spectroscopy (FTIR) has been used to characterize inductively coupled CF4 plasmas in a GEC Reference Cell in-situ In examining these FTIR spectra, several assumptions What is FTIR? FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted).
