Quality Control

Our Samarium Tris(2-Ethylhexanoate) is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including titration, inductively coupled plasma optical emission spectrometry (ICP-OES) for metal content, and infrared spectroscopy (IR) for identification. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the container to reach room temperature before opening to minimize moisture ingress.
