Description

Barium138 is a stable isotope of barium, specifically the isotope with mass number 138, identified by CAS No. 15010-01-2. This high-purity isotopic material is critical for applications requiring precise atomic mass and minimal isotopic interference, serving as a fundamental standard in analytical and research fields. It is primarily utilized by research institutions, analytical laboratories, and advanced manufacturing sectors involved in nuclear science, geochemical tracing, and the calibration of mass spectrometry equipment.

Application

• Primary Standard for Mass Spectrometry: Used as a calibration standard and spike material in isotope dilution mass spectrometry (ID-MS) for precise quantitative analysis.
• Nuclear Research & Development: Serves as a target material or a stable tracer in nuclear physics experiments and reactor studies.
• Geochemical and Environmental Tracing: Employed as a stable isotopic tracer in studies of earth processes, sediment dating, and environmental pollutant transport.
• Medical Research: Potential use in the development of diagnostic agents and in metabolic studies where a non-radioactive barium tracer is required.
• High-Purity Material Production: Acts as a precursor for synthesizing other high-purity barium compounds with defined isotopic composition.
• Analytical Chemistry: Used to prepare reference materials and standards to ensure accuracy and traceability in elemental analysis.
