Quality Control

Our Lanthanum Fluoride Oxide, 99.999% (Reo) is produced under stringent conditions to guarantee batch-to-batch consistency and traceability. Quality is verified through advanced analytical techniques including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and X-ray Diffraction (XRD). A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical characteristics is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture and CO₂, which can affect product quality.
