Quality Control

Our Erbium Trihydroxide is manufactured under controlled conditions to ensure high chemical purity and batch-to-batch consistency. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, and thermogravimetric analysis (TGA). A Certificate of Analysis (COA) detailing purity, trace metal content, and physical characteristics is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and caking. Recommended storage temperature is 15-25°C.
