Quality Control

Our analytical reagent grade Dimethylglyoxime Disodium Salt is manufactured under strict quality protocols. Each batch undergoes comprehensive testing to ensure it meets high-purity standards suitable for sensitive gravimetric and colorimetric analysis. A Certificate of Analysis (COA) detailing purity, assay, and specific tests is provided with every shipment to guarantee traceability and consistency for your laboratory procedures.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed immediately after use to prevent moisture absorption, which can affect purity and performance.
