For quantitative PC analysis by ATR-IR the PC/clay absorption intensity ratios were calibrated by collecting IR spectra of physical mixtures of clay with known 

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.
