The molecular weight and structure of a polymer influences processing behavior and physical properties of the finished product. Understanding your polymer is essential for novel polymer synthesis and development, or good material performance.

GPC testing, also known as Size Exclusion Chromatography (SEC), is the best technique to characterize the whole polymer distribution.

GPC Testing at Smithers

Our extensive capabilities and expertise allows Smithers to characterize most polymer types through GPC testing. Each request we receive is in some way unique. Smithers GPC experts will discuss with you the best approach to your issue.

Using our state-of-the-art instrumentation at our rubber and plastic testing labs, our expert team will employ these techniques to help you:

  • Understand the fundamental composition and structure of your polymer, polymerization and catalysis processes.
  • Analyze polymer degradation
  • Contribute to diagnosis of material or product failure
  • Realize batch to batch variance and quality control for polymer production and processing
  • Assist in a material selection exercise
  • Assist to provide data necessary to support registration of new product as a polymer
