Materials Characterization Laboratories
Materials characterization combines structural, thermal, mechanical, surface and chemical techniques to build a documented property picture of a material or product.
Reference versus candidate medical plastics and colorants
Compare the reference and candidate finished components, documented resin identity when available, pigment/dye or additive changes, manufacturing and cleaning/sterilization histories, and actual exposure. Unknown composition, sample allocation and test panels remain questions to resolve—not inferred facts. Material identification and color comparison do not establish biological safety.
Propose methods around the evidence gap
Ask the provider whether FTIR, DSC or other material identification, targeted chemistry, extraction studies and toxicological interpretation can answer the comparison question. These are possible proposals, not prescribed tests. Biological compatibility, chemical/material resistance and product interactions are different scopes. A qualified evaluator should justify existing evidence, chemical characterization and any targeted biological testing after a material or colorant change.
Sample considerations
- Provide enough material for a technique set rather than a single test.
- Record processing history — it affects most measured properties.
