Quality Control

Every batch of our conjugated polymers is synthesized and purified under controlled conditions to ensure consistent molecular weight, polydispersity, and end-group fidelity. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC), Nuclear Magnetic Resonance (NMR), and UV-Vis spectroscopy. Certificates of Analysis (COA) detailing batch-specific properties are provided to guarantee material performance for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Keep away from heat and incompatible materials.
