Quality Control

Every batch of our conjugated polymers is synthesized and purified under strictly controlled conditions to ensure consistent performance. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, Nuclear Magnetic Resonance (NMR) for structural confirmation, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing batch-specific properties such as purity, regioregularity, and optical characteristics is provided with each shipment to support your 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 (e.g., nitrogen or argon) to prevent oxidation and degradation. Keep away from heat and incompatible materials.
