Quality Control

Every batch of our conjugated polymers is synthesized and purified under strictly controlled conditions to ensure high molecular weight consistency, controlled polydispersity, and minimal metallic/ionic impurities. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC), Nuclear Magnetic Resonance (NMR), and Elemental Analysis. A comprehensive Certificate of Analysis (COA) detailing molecular weight, purity, and spectral data 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 a controlled 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.
