Quality Control

Our Rubidium Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical testing, including assay, impurity profile analysis (by ICP-MS/AAS), and physical characterization. A Certificate of Analysis (COA) detailing all test results is supplied with each shipment, and we can support compliance with relevant standards such as USP, ACS, or custom specifications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials.
