Unknown Components

Isolation and identification of unknown components and impurities.
Depending on the product application, the presence of an unknown component or impurity at even trace levels can cause irreparable damage to a product, rendering it unusable. Unknown components and impurities can appear from several sources and, once present, can be extremely difficult to remove. Impact Analytical’s full breadth of analytical capabilities and 30+ years of experience characterizing unknowns and impurities enable us to solve these tough problems. We have proven methodologies for specific material types that allow us to efficiently isolate and identify the material, followed by determining its source.

Unknown and impure materials can come from numerous sources, including:

Process contaminants

  • API and/or non-active component degradation
  • Oxidated polymer additives
  • Un-reacted monomers/oligomers
  • Extractables/Leachables
