Rubidium-87 (⁸⁷Rb) Suppliers in China - Long-Lived Isotope from Reliable Factory for NMR Applications

Basic Nuclear Properties of Rubidium-87
Rubidium-87 (⁸⁷Rb) is a natural radioactive isotope of rubidium, abundantly found in nature with an approximate abundance of 27.83%, alongside the stable isotope ⁸⁵Rb. Known for its long half-life of 4.97×10⁵ billion years (T₁/₂), this nuclide undergoes β⁻ decay, ultimately producing the stable isotope ⁸⁷Sr. During its decay process, it emits β particles with a peak energy of 283 keV. Rubidium-87 possesses a nuclear spin of I=3/2 and a significant nuclear magnetic moment of μ=2.751 μₙ, making it highly advantageous for applications in nuclear magnetic resonance (NMR) research. Our factory in China specializes in the production and supply of high-quality rubidium isotopes, serving as trusted suppliers for various industrial and research needs.

    Application in geochronology

    The ⁸⁷Rb-⁸⁷Sr decay system is one of the important methods of radioactive dating and is suitable for dating ancient rocks (such as granite and meteorites). Its decay constant λ=1.42×10⁻¹¹ yr⁻¹. By measuring the ratio of ⁸⁷Sr/⁸⁶Sr and ⁸⁷Rb/⁸⁶Sr, combined with the isochron method, the geological age can be calculated, and the time span can reach billions of years. This technology plays a key role in studying the evolution of the earth's crust, the formation history of the moon and meteorites.

    Atomic physics and quantum technology

    ⁸⁷Rb is one of the core elements of cold atomic physics, and its D₂ line (780.24 nm, 5²S₁/₂→5²P₃/₂ transition) is a common transition in laser cooling and Bose-Einstein condensation (BEC) experiments. The ground state hyperfine structure (F=1,2) of ⁸⁷Rb can be used for precision measurements, such as atomic clocks (rubidium atomic clock frequency standard ~6.834682 GHz) and quantum simulation experiments. In addition, the Feshbach resonance characteristics of ⁸⁷Rb make it attract much attention in ultracold molecular preparation and quantum many-body research.

    Medical and tracer applications

    ⁸⁷Rb can be generated by neutron activation of ⁸⁶Rb (n,γ), and its short-lived isotope ⁸²Rb (T₁/₂=1.27 min) is a myocardial perfusion imaging agent for positron emission tomography (PET) and is used for the diagnosis of coronary heart disease. Although ⁸⁷Rb itself is not directly used in medicine, its decay chain products (such as ⁸⁷Sr) have certain reference value in bone metabolism research.

    Nuclear safety and handling

    ⁸⁷Rb has weak radioactivity (specific activity ~3.2×10⁻⁴ Bq/g), and usually does not require special protection, but long-term exposure to high-concentration ⁸⁷Rb compounds (such as RbCl) still needs to be avoided from inhalation or ingestion. In the laboratory, ⁸⁷Rb is often stored in the form of chloride or carbonate and needs to be sealed to prevent moisture.

    Conclusion

    ⁸⁷Rb, as an important long-lived radionuclide, plays an irreplaceable role in geochronology, cold atomic physics and nuclear medicine. Its unique performance in quantum precision measurement technology indicates its potential application value in quantum computing and high-precision sensing in the future.
    Frequently Asked Questions (FAQ)

    What is the decay constant of ⁸⁷Rb and how is it used?

    The decay constant of ⁸⁷Rb is λ=1.42×10⁻¹¹ yr⁻¹. It is used in the ⁸⁷Rb-⁸⁷Sr decay system alongside the isochron method to calculate the geological age of ancient rocks, meteorites, and the earth's crust, spanning up to billions of years.

    Why is ⁸⁷Rb important in atomic physics and quantum technology?

    ⁸⁷Rb is a core element in cold atomic physics. Its D₂ line (780.24 nm) is widely used in laser cooling and Bose-Einstein condensation (BEC) experiments, while its ground state hyperfine structure is utilized in precision measurements like rubidium atomic clocks (~6.834682 GHz).

    How does ⁸⁷Rb relate to medical imaging?

    While ⁸⁷Rb itself is not directly used, its neutron activation process relates to the short-lived isotope ⁸²Rb (T₁/₂=1.27 min), which serves as a myocardial perfusion imaging agent in PET scans to diagnose coronary heart disease.

    Is ⁸⁷Rb dangerous or highly radioactive?

    No, ⁸⁷Rb has very weak radioactivity with a specific activity of approximately 3.2×10⁻⁴ Bq/g. It generally does not require special safety protection, though long-term exposure to high concentrations should be avoided.

    How should ⁸⁷Rb compounds be stored in a laboratory setting?

    In laboratories, ⁸⁷Rb is commonly stored as chloride (RbCl) or carbonate compounds. These storage containers must be tightly sealed to prevent moisture degradation.
