Quality Control

Our 1-Ethyl-1-Methylpyrrolidinium Hexafluorophosphate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity for demanding electrochemical applications. We provide comprehensive analytical testing, including HPLC, Karl Fischer titration, and ion chromatography, to verify key parameters such as assay, moisture content, and halide impurities. A Certificate of Analysis (COA) documenting all specifications is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture absorption.
