Characterization or chemical identification of materials can be determined using Differential Scanning Calorimetry (DSC) techniques, Fourier Transformed Infrared Spectroscopy and Dispersive X-Ray Spectroscopy.

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.

TESTS METHODS
Oxidative Induction Time by High Pressure DSC ASTM D5885
Thermal Stability by DSC ASTM E5378-86
Transition Temperature by DSC ASTM D3418
Transition Temperature of Polymers by DSC ASTM D3417
Specific Heat of Liquid & Solid by DSC ASTM D3947
 

FOURIER TRANSFORMED INFRARED SPECTROSCOPY (FTIR) generates a spectrum from which chemical identification of materials is possible. It 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. It also identifies the material chemically from its unique spectrum.

TESTS METHODS
Cure Study by DSC and FTIR
Chemical Characterization by FTIR
Failure Analysis by FTIR
