The amount of other lithium isotopes present are related to the 6 Li content through the following certified amount ratios: 6 7 n( Li)/n( Li) : 21.897(44) This corresponds to an isotopic composition of lithium with the following abundances: amount fraction (·100) mass fraction (·100) ...
Naturally occurring lithium is composed of two stable isotopes, 6Li and 7Li, the latter being the more abundant (92.5% natural abundance). A természetben előforduló lítiumnak két stabil izotópja van, a 6Li és a 7Li, ezek közül a 7Li a gyakoribb (természetes előfordul...
This technique enables rigorous corrections of mass discrimination by spiking with an artificial solution enriched in two or three Pb isotopes (e.g., 207Pb–204Pb). However, the problem of impurities in separated Pb samples remains even in the double-spike method for measuring small sample sizes...

A tracer is a molecule that is sufficiently similar to (ideally, chemically indistinguishable from) the original substance under study, but where one or more atoms in the structure have been replaced with isotopes (labels) that are in low natural abundance and thus suitable to tracking [5,6]....
