DIFFERENTIAL SCANNING CALORIMETRY (DSC) by THERMAL ANALYSIS is a technique in which, upon heating or cooling a material, energy is absorbed or released as the material experiences physical or chemical changes. DSC measures heat absorbed and released, calculates heat of fusion and percent of crystallinity and oxidative induction times (OIT). DSC defines the unique characteristics of geosynthetic materials.

FOURIER TRANSFORMED INFRARED SPECTROSCOPY (FTIR) generates a spectrum from which chemical identification of materials is possible. Identifies the material chemically from its unique spectrum if there is contamination or impurity on a material or chemical degradation, new chemical functional groups are formed and can be detected by FTIR. Identifies the material chemically from its unique spectrum.
