Description

Potassium41 CAS NO 13965-93-0 is a stable isotope of potassium, specifically the potassium-41 (41K) isotope. This material is critical for research and industrial applications requiring precise isotopic labeling or tracing, where the natural abundance of 41K is insufficient. It is primarily utilized by analytical laboratories, academic research institutions, and advanced material science developers working in fields such as geochemistry, biochemistry, and nuclear magnetic resonance (NMR) spectroscopy.

Application

• Isotopic Tracer Studies: Used as a stable tracer in biological, environmental, and geological research to track potassium pathways and cycles.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as a valuable tool in NMR for studying potassium ion channels and binding sites in biological systems.
• Reference Standard for Mass Spectrometry: Employed as a high-purity calibration standard in isotope ratio mass spectrometry (IRMS) and inductively coupled plasma mass spectrometry (ICP-MS).
• Advanced Material Development: Used in the synthesis of specialized materials where specific isotopic composition affects physical properties.
• Geochemical Dating and Analysis: Applied in potassium-argon (K-Ar) and argon-argon (Ar-Ar) dating methods as a key component.
• Medical and Pharmaceutical Research: Potential use in metabolic studies and the development of novel diagnostic agents.

Quality Control

Our Potassium41 is produced and handled under stringent quality protocols to ensure exceptional isotopic and chemical purity. Each batch is analyzed using advanced techniques such as mass spectrometry to verify isotopic enrichment and to control for metallic impurities. A comprehensive Certificate of Analysis (COA) detailing isotopic purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your research specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere such as argon or nitrogen in a cool, dry place. Recommended storage temperature is 15-25°C. Keep away from incompatible materials.
