Quality Control

Every batch of our conjugated polymers is synthesized and purified under controlled conditions to ensure consistent performance and high purity. Our quality assurance protocol includes characterization of molecular weight (GPC), end-group analysis, and assessment of electronic properties. Certificates of Analysis (COA) detailing batch-specific data including purity, molecular weight distribution, and spectral identification are provided. We adhere to stringent in-process controls to meet the exacting requirements of advanced materials research and production.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C to -10°C under an inert atmosphere (argon or nitrogen) to minimize oxidation and prolong shelf life. Allow the sealed container to reach room temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
