dilution method, whereby known amounts of isotopically substituted compounds are mixed with the samples and the isotopic signatures of the resulting mixtures...

Look up isotopic in Wiktionary, the free dictionary. Isotopic may refer to: In the physical sciences, to do with chemical isotopes In mathematics, to do...

amounts of isotopically enriched substance to the analyzed sample. Mixing of the isotopic standard with the sample effectively "dilutes" the isotopic enrichment...

taken advantage of in isotope geochemistry and other fields. Normally, the focus is on stable isotopes of the same element. Isotopic fractionation can be...

simultaneously. Because enriched isotope preparations are never isotopically pure, i.e. they contain all the element's isotopes in unnatural abundances, calculations...

Natural nitrogen (7N) consists of two stable isotopes: the vast majority (99.6%) of naturally occurring nitrogen is nitrogen-14, with the remainder being...

Gold (79Au) has one stable isotope, 197Au, and 37 radioisotopes, with 195Au being the most stable with a half-life of 186 days. Gold is currently considered...

There are three known stable isotopes of oxygen (8O): 16 O , 17 O , and 18 O . Radioactive isotopes ranging from 11 O to 28 O have also been characterized...

Isotope analysis is the identification of isotopic signature, abundance of certain stable isotopes of chemical elements within organic and inorganic compounds...

occurring isotopes, sometimes denoted 1 H , 2 H , and 3 H . 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. Heavier isotopes also exist...

Isotope 217° is a Chicago-based band composed mainly of members from Tortoise and the Chicago Underground Orchestra that was formed in 1997. The New York...

naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives...

produced from Lithium-6 which is often enriched for this purpose, too. Some isotopically purified elements are used in smaller quantities for specialist applications...

CO2 can be converted to methane and from there to isotopically pure synthetic diamonds. Isotopically enriched diamonds have been synthesized by application...

A medical isotope is an isotope used in medicine. The first uses of isotopes in medicine were in radiopharmaceuticals, and this is still the most common...

Caesium (55Cs) has 41 known isotopes, the atomic masses of these isotopes range from 112 to 152. Only one isotope, 133Cs, is stable. The longest-lived...

it has no stable isotopes. The first isotope to be synthesized was 289Fl in 1999 (or possibly 1998). Flerovium has six known isotopes, along with the unconfirmed...

The Albuquerque Isotopes are a Minor League Baseball team of the Pacific Coast League and the Triple-A affiliate of the Colorado Rockies. They play home...

Although there are nine known isotopes of helium (2He) (standard atomic weight: 4.002602(2)), only helium-3 (3 He ) and helium-4 (4 He ) are stable. All...

one of its isotopes. Formally, it is the ratio of rate constants for the reactions involving the light (kL) and the heavy (kH) isotopically substituted...
