Quality Control

Every batch of our conjugated polymers is synthesized and purified under controlled conditions to ensure consistent molecular weight, polydispersity index (PDI), and electronic performance. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC), Nuclear Magnetic Resonance (NMR) spectroscopy, and UV-Vis spectroscopy. Certificates of Analysis (COA) detailing batch-specific properties are available upon request to support your research and quality assurance protocols.

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 such as nitrogen or argon to prevent oxidation and degradation. Keep away from heat and incompatible materials.
