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.
