  2. Rubidium - Wikipedia

    en.wikipedia.org/wiki/Rubidium

    Rubidium chloride (RbCl) is probably the most used rubidium compound: among several other chlorides, it is used to induce living cells to take up DNA; it is also used as a biomarker, because in nature, it is found only in small quantities in living organisms and when present, replaces potassium.

  3. Rubidium chloride - Wikipedia

    Rubidium chloride is the chemical compound with the formula RbCl. This alkali metal halide salt is composed of rubidium and chlorine , and finds diverse uses ranging from electrochemistry to molecular biology .

  4. Rubidium standard - Wikipedia

    en.wikipedia.org/wiki/Rubidium_standard

    Commercial rubidium clocks are less accurate than caesium atomic clocks, which serve as primary frequency standards, so a rubidium clock is usually used as a secondary frequency standard. Commercial rubidium frequency standards operate by disciplining a crystal oscillator to the rubidium hyperfine transition of 6.8 GHz (6 834 682 610.904 Hz).

  5. Rubidium-82 - Wikipedia

    en.wikipedia.org/wiki/Rubidium-82

    Rubidium-82 (82 Rb) is a radioactive isotope of rubidium. 82 Rb is widely used in myocardial perfusion imaging . This isotope undergoes rapid uptake by myocardiocytes , which makes it a valuable tool for identifying myocardial ischemia in Positron Emission Tomography (PET) imaging.

  6. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    Atomic clocks based on rubidium standards are therefore regarded as secondary representations of the second. Rubidium standard clocks are prized for their low cost, small size (commercial standards are as small as 1.7 × 10 5 mm 3) [33] and short-term stability. They are used in many commercial, portable and aerospace applications.
