Quality Control

Our Ruthenium Sulfate is produced and tested under strict quality management protocols. We ensure batch-to-batch consistency through comprehensive analysis, including assay (Ruthenium content), impurity profiling via ICP-MS, and physical characterization. A Certificate of Analysis (COA) detailing purity, heavy metal limits, and other critical parameters is provided with each shipment to guarantee it meets your specific application requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
