Enriched stable isotopes of potassium (K, Z = 19): 3 isotopes with enrichment up to 99.98 at.% (³⁹K). Chemical form: chloride. Packaging from milligrams; every lot comes with a passport stating its isotopic and chemical composition.
| Isotope | Enrichment, at.% | Chem. purity, % | |
|---|---|---|---|
| ³⁹K | 99.98 | > 99.91 | |
| ⁴⁰K | 8.90 | > 98.00 | |
| ⁴¹K | 99.10 | > 98.00 |
Enrichment is the atomic fraction of the target isotope, %. Data are given according to the producer’s specification; the exact composition of a lot is stated in its passport. Availability, packaging and price on request. Export of isotope products is subject to export control requirements.
| ³⁹K | tracers in potassium metabolism studies, standards |
| ⁴⁰K | primordial long-lived radionuclide (T½ ≈ 1.25 billion years): potassium–argon dating, calibration, research |
| ⁴¹K | tracer in biomedical potassium studies |
Reference information on typical applications. Please confirm the suitability of the isotope for your task (enrichment, chemical form, quantity) in your request.
