Description

Zirconium91 CAS NO 14331-93-2 is a high-purity, stable isotope of zirconium, specifically the isotope with mass number 91. This material is critical for advanced research and industrial applications where isotopic purity and traceability are paramount. It is essential for nuclear science, materials research, and as a tracer in geochemical and environmental studies.

Application

• Nuclear Science & Engineering: Used as a target material or tracer in neutron activation analysis and nuclear reaction studies.
• Advanced Materials Research: Serves as a precursor for synthesizing isotopically-enriched zirconium compounds to study material properties without interference from other isotopes.
• Geochemical Tracers: Employed in isotopic dilution mass spectrometry (ID-MS) to accurately determine zirconium concentrations and study geological processes.
• Environmental Science: Acts as a stable isotopic tracer to monitor the transport and fate of zirconium in environmental systems.
• Metallurgy: Used in specialized alloy development where specific isotopic composition can influence material behavior under extreme conditions.
• Reference Standards: A key component in the production of certified reference materials (CRMs) for analytical calibration and quality assurance.

Quality Control

Our Zirconium91 is produced and handled under stringent quality protocols to ensure exceptional isotopic and chemical purity. Each batch is characterized using advanced analytical techniques, including Inductively Coupled Plasma Mass Spectrometry (ICP-MS), to verify isotopic enrichment and trace metallic impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic abundance, chemical purity, and analytical methods is provided with every 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). Keep away from incompatible materials such as strong acids and strong oxidizing agents. For long-term storage, maintain under an inert atmosphere to prevent surface oxidation.
