Characterization of contaminants in different materials


Examples of products in which contaminants have been identified include:

  • automotive parts and vehicles
  • beverages, food and others
  • filters showing abnormally high concentrations of residues or sediments
  • raw materials
  • packaging
  • textiles, papers, plastics and others
  • industrial process wastes
  • plastics with liquid coatings
IPT characterizes contaminants in different materials, using infrared spectrophotometry as the main technique to identity the origin of the contaminant.
